Hive Scale Research in the Raleigh Area

Beekeepers keep bees for lots of different reasons, some for a livelihood, others for the honey, but no matter the reasoning, everyone who works with bees is fascinated by them. New technologies such as hive scales can open new insights into what the bees are doing. In addition to potentially learning more about how our colonies are growing and developing, can hive scales provide us additional information that can inform our beekeeping management? Does new technology open up new avenues to not only better understand and appreciate these remarkable creatures, but can it also help us become better beekeepers?

To answer some of these questions, the Bayer Bee Care program is partnering with local beekeepers to better understand the forage availability in the local Raleigh/Durham area using the power of hive scales. We are providing beekeepers in Orange, Durham, Wake, Johnston, Granville, Franklin, Wilson, Chatham and Nash County with electronic hive scales to follow hives throughout the year. Beekeepers will upload hive weight data on a regular basis to share what’s going on in their hives across the region. In the fall after the aster bloom is over, Bayer will use this data with GIS analysis of the apiary within the hive’s foraging range to assess effects of land cover on the timing of nectar flows and the magnitude of weight gain during flows. We hope to get a better idea of how different degrees of development/urbanization, forest and cropland affect the timing, intensity, and duration of nectar flows. By understanding what floral resources bees have access to and when, we hope to help the local beekeeping community better anticipate the nutritional needs of their hives.

Weekly Updates

Week 11:

This week I had 30 scales to report on which I have split into the following 4 groups: 1) greater than 145 lbs, 2) 100-145 lbs, 3) 80-100 lbs, and 4) Less than 80 lbs.

Week 11 Hive Scale Research Graph Greater Than 145 Lbs

 Week 11 Hive Scale Research Graph 100-145 Lbs

Week 11 Hive Scale Research Graph 80-100 Lbs

Week 11 Hive Scale Research Graph Less Than 80 Lbs

So this week is a different story from last week! Instead of weights dropping, a lot of people are seeing weight gains. Johnston-2 and Granville-1 in the 100-145 lb group both gained around 15 lbs!

The past few days we’ve seen lots of precipitation so let’s revisit the empty equipment:

Week 11 Hive Scale Research Graph Empty 

I am amazed by a 2 lb weight fluctuation on both June 17th and 18th and very interested in better understanding this phenomenon. I am starting several other projects in the following week that will hopefully provide more insight into weight changes from changing environmental conditions, as well as general insight into food storage, stay tuned!

I also want to announce that my colleague, Allen, and I will be attending the NCSBA/SCSBA meeting next month and will be leading a workshop on electronic hive scales to discuss what we have seen so far with this project! Once I have the specific date and time I will be sure to let everyone know. I am very interested in getting new perspectives and hearing feedback from those involved and those who may have been thinking about weight data and following the project. Hope to see you there!

Week 10

This week I had 33 scales to report on which I have split into the following 4 groups: 1) greater than 145 lbs, 2) 110-145 lbs, 3) 80-110 lbs, and 4) Less than 80 lbs.

Week 10 Bee Hive Scale Graph Greater Than 145 Lbs

 Week 10 Bee Hive Scale Graph 110-145 Lbs

Week 10 Bee Hive Scale Graph 80-110 Lbs

Week 10 Bee Hive Scale Graph Less Than 80 Lbs

So this week the trend is either flat or declining overall, except for some slight weight gains for Johnston-2, Caswell-2, and Granville-1. With that being said, it looks like it might be time to start supplementally feeding!

Buckets of honey for hive scale researchNow at this point, I know some of the scales have moved around to different hives or to hives have changed locations. I will try to indicate when that occurred (if it’s not obvious) on the running graphs. And now that the spring flow has ended, I will start looking back at the management records to try and pull out changes in the hives, and how that may have changed the weight. I will also start working with the GIS team to prepare the land cover assessments. Each beekeeper will receive a map of the 5 mile radius around their apiary but I will only report the percentages for that apiary on the website. Lots to do and so little time!

This week I have been busy harvesting buckets and buckets of honey from supers we took off of hives involved in a separate project. After looking at the weight gains throughout the season from all of the hives, I had a new found appreciation for what the bees can accomplish in a week let alone in a month! I want to take a minute and put a 5 lb weight gain into perspective through some fun pictures!

A single plastic frame (left), pulled out completely on both sides and filled past the sides of the frame weighed in at 9.6 pounds! A completely filled frame pulled out and flush to the sides of the frame (right) weighed in at 7.9 pounds.

Honeycomb Weighing 2.55 LbsNow after extracting a frame (left), the plastic frame and drawn comb weighs in just over 2.5 pounds. So the capped honey frame on the left is what 7 pounds of honey looks like, and the one on the right is what 5 pounds looks like (front and back of course).

I’ve been lifting supers and honey frames for years but for some reason, now knowing the weight of these frames, I have such an appreciation for all the energy that goes into a single frame of honey! I also feel pretty muscular knowing I’ve been schlepping around 70 lbs of honey (plus the weight of the equipment) all week!

Week 9

This week I had 32 scales to report on which I have split into the following 4 groups: 1) greater than 145 lbs, 2) 110-145 lbs, 3) 80-110 lbs, and 4) Less than 80 lbs.

Honey Harvest 2017 Spreadsheet 

Well it seems pretty clear to me that the major spring flow has ended. This week the trend is either no change or a slow decline in weight. Although, looking at overall trends when preparing the running graphs for May (shown at the bottom of the page), I was amazed by how much weight hives had put on since April! Some hives, like Wake-3 and Wake-9 more than doubled in size, and across the board, a 50 lb weight gain seemed to be the norm!

I am still working on understanding last week’s weather anomaly and getting access to weather station data so that special feature is slightly behind schedule. One of the reasons for my delay is a new found interest in pollen ID’s, sparked by the curiosity of a Halifax beekeeper! After seeing a big difference in the color of the honey he extracted this year, he contacted me asking if we could analyze honey. My colleague and partner on this project, Allen Olmstead, has been interested in ID-ing pollen from honey for quite some time now so we decided to give it a try here at the bee care center. I will report back in an additional special feature on how it went!

Week 8

This week I had 34 scales to report on which I have split into the following 5 groups: 1) greater than 175 lbs, 2) 130-175 lbs, 3) 110-130 lbs, 4) 85-110 lbs, and 5) Less than 85 lbs. With people harvesting or breaking down hives (some have gone queenless) causing substantial jumps in weight, I have grouped hives by their end weight rather than the weight at the start of the week. And in the case of Caswell-Prospect Hill, they jumped from 338 to 176 lbs so I only plotted the past several days at 176 lbs to save room. That’s a lot of honey!

Week 8 Bee Research Honey Harvest Table 

Purple flower in a fieldSimilar to last week, most of the hives are largely holding steady at this point in the season with the exception of Martin 2, 3, and 4 which are out near the coast in sage fields! As you can see, sage is an excellent resource for them at this time of year, allowing them to gain 10-15 lbs in just 3 days! For anyone who has not heard of sage production in North Carolina or maybe not even seen a sage flower before (I certainly had not!), here is a picture from the field around one of these hives. So plenty to feed on for these ladies!

This week we have some substantial weight losses, with some hives like Orange-2 and Caswell-2 losing 10-15 lbs. Several beekeepers have had their hives swarm and others have lost queens these past few weeks so it’s hard to tell what’s happening at the moment.

An anomaly I noticed this week is the sudden weight drop on May 25th in a lot of the hives. I’m guessing this is weather related rather than bee related based on the same weight drop in the empty equipment:

Week 8 Bee Research Graph Empty 

I am so intrigued by this weight change that I’m going to take a deeper dive into what’s going on here in the next special feature! I am going to pull in weather station data from here at the bee center and nearby areas and look through management notes to see if the magnitude of the weight change is related to the type of equipment folks are using. Keep an eye out for that early next week! The more we understand how to interpret weight data and the limits of these interpretations, the more informed we can be when managing our bees!

Week 7

This week we have 35 scales to report on but several new beekeepers getting involved! As a reminder, this year we are seeing what all we can get out of the weight data and get a sense of how to assess relationships with land cover. Hopefully if people remain interested in this work, we can improve our study design and refine our approach for data collection next year. So although we will have likely missed the major flow events in these newly added locations, these beekeepers will be setup for the rest of the bee season and ready to go for the spring!

So this week I had to put Big Bertha in a group of her own now that Halifax-3 harvested close to 100 lbs of honey! But I have split the other 34 hives into four groups as follows: 1) 150-200 lbs, 2) 100-150 lbs, 3) 50-100 lbs, and 4) Less than 50 lbs. With people harvesting honey and jumping weight classes, there was quite a spread within groups. I caution everyone to look at the axes very closely: the y-axis scale for the 150-250 lb group is in 20 lb increments as opposed to 10 lbs in the 100-150 and 50-100 lb groups and 2 lb increments for Big Bertha and the Franklin hives less than 50 lbs.

Bee Research Graph Less than 50 Lbs

With people removing supers it’s not as clear in the graphs what’s going on so for those who I can clearly see harvested, I’ve put together a table for how much weight they removed and the weight of the hive before harvest. I will add to this table as others start to harvest as well so we can compare across the regions!

Bee Research Table Week 7 

I think a table might also be a better way to highlight the hives that stand out for their weight gains this week instead of writing out a whole list of names! I used different colors for each weight class to hopefully make it easier to differentiate!

Bee Research Table Week 7

Most of the other hives across the board are holding very steady, fluctuating less than half a pound in the course of a week! Which when you think back to the empty hive, is rather surprising actually.

Bee Graph Empty

I am always left with more questions than answers when looking at this weight data! Are the bees buffering the weight changes attributed to equipment? In the case of Nash-3, a 70 lb hive has put on a fifth of its’ original weight within the same week that a 230 lb hive, with presumably 3X the work force, has put on the same amount of weight. How is this hive putting on so much weight when hives just down the road, 1.5X as large, are gaining practically nothing? I don’t think I ever fully appreciated how limited the bees are to whatever is blooming in that 5 mile radius from their hive!

Week 6

This week we have 34 scales to report on. Once again, with the spread in weights, I split them into five groups as follows: 1) Greater than 200 lbs, 2) 150-200 lbs, 3) 100-150 lbs, 4) 50-100 lbs, and 5) Less than 50 lbs. This week things really look like things have slowed down and several folks are talking about harvesting!

I also want to include the weight readings from the empty deep box (no frames) again:

Bee hive empty equipment graph. 

It’s very interesting to see these 1 lb daily weight fluctuations with sharp declines after reaching the peak weight!

Overall weights appear to be relatively flat with only small daily fluctuations however “Big Bertha” at 340 lbs is still putting on weight! I imagine folks will start removing supers at this point so I expect to see some dramatic drops in weight over the next few weeks!

Week 5

This week we have 33 scales to report on. There was such a wide spread in the weights that I split them into five groups this week as follows: 1) Greater than 250 lbs, 2) 150-250 lbs, 3) 100-150 lbs, 4) 75-100 lbs, and 5) Less than 75 lbs. If you recall, in the Week 2 update, we saw the first substantial evidence of the spring nectar flow right around April 11th. It’s been about a month since then and it looks like the speed of weight gain is slowing down in most areas. The weather could certainly be a confounding variable since this past week has been cooler and wetter than the past few weeks.

 Week 5 150-250 lb bee chart.

Week 5 100-150 lb bee chart.

Week 5 75-100 lb bee chart.

Week 5 less than 75 lbs bee chart.

Something that jumps out to me is the “bump” in the data on May 5th, seen most clearly in Chatham-1, Orange-4, Orange-Ref1, and Nash-1 in the 75-100 lb group, Nash-2, Wake-7, Wake-4 and Orange-1 in the 100-150 lb group, and Wake-2, Johnston-2, Orange-Ref2, Halifax-1, and Halifax-2 in the 150-250 lb group. My thinking is that this is weather related. So to explore this idea, last week I set up an empty deep box (no frames) with a screened bottom board on a scale here at the Bee Care Center.

Week 5 empty deep box chart. 

Now this starts to raise even more questions..with just an empty deep box and a lid, there is a ~2 pound weight gain the day before the “bump” in the data. However this 2lb spike on May 4th coincides with the timing of a ~4 lb increase in Orange-1, a 2 lb increase in Caswell-2, and a 4 pound increase in Durham-1, within the 75-100 lb group, and a 3 lb increase in Nash-3 in the less than 75 lb group. I will start looking into local weather station data to see if this corresponds to different weather events in different regions and set up more empty equipment, some with nectar frames, to better understand how the weight of the equipment and woodenware changes during precipitation events. It will be important to know how much the equipment is attributing to weight changes during these events and how much is bee activity!

Week 4

This week we have 31 scales to report for in the following weight classes: 1) greater than 150 lbs, 2) 100-150 lbs, 3) 50-100 lbs, and 4) less than 50 pounds. Several beekeepers have joined the project with some massive honey producing hives! Halifax-3 was the largest this week at close to 260 lbs and next week I will be able to report on Caswell-Prospect Hill aka Big Bertha weighing in at 320 lbs! Now keep in mind, these folks have larger operations than their backyard and are working these hives to maximize honey production. When a state bee inspector was asked how to maximize honey production his answer was simple: location is key. You have to move your hive as different flowering plants/crops start blooming, and that’s what these folks are doing.

Week 4 greater than 150 lbs

 Week 4 between 100-150 lbs

Week 4 between 50-100 lbs

Week 4 Less than 50 Lbs 

Despite the rain the previous week, the bees are back out on the tulip poplar, blackberry, black locust, honey suckle, southern magnolia and other blooming nectar sources! Most of the hives weighing greater than 150 lbs groups have put on around 20 lbs in the past week! Hives in the 100-150 lbs group are very variable with some of the hives (Nash-1, Orange-1, Wake-2, Wake-4) steadily gaining 5 lbs, and the other half (Caswell-1, Orange-3, Wilson-1, Wake-7, Johnston-2) gaining over 10 lbs. Interestingly this week, where normally we see a decrease in the magnitude of weight gain in the lighter hives, here in the 50-100 lbs group we see some hives gaining 10-20 lbs (Caswell-2, Orange-2, Wake-12). There’s a lot of noise in the other hives within this group so I hesitate to overanalyze what’s going on with these hives. The other surprise this week is Wake-10, which started at less than 50 lbs and has gained 10 lbs this week! The other hives in this group appear to be holding steady at this point.

Week 3

Participation with this project has grown tremendously since I first reached out to folks! Thanks to those beekeepers who have spread the word, we are now up to 46 scales with 34 beekeepers, representing 18 different counties! Some folks have locations in more remote areas, rather than or in addition to their backyard, so some of the scales won’t be included in every week’s update but their data will be shown in the running graphs at the bottom of the page as they upload. And of course all of the data collected will be used in the final report to analyze the effects of land cover.

Week 3 Swarming

>>Learn more

This week, we have data from 24 hive scales from April 18-April 25th, and with the spring flow in full swing, we already have to bump up the weight classes! So this week the hives didn’t separate out as cleanly but the 4 different approximate weight classes are as follows: 1) Less than 50 lbs, 2) 50-85 lbs, 3) 85-130 lbs, 4) Greater than 130 lbs.

Week 3 hive scale graph over 130 lbs


Week 3 hive scale between 85-130 lbs


Week 3 hive scale graph under 50 lbs


Week 3 hive scale graph less than 50 lbs 

Similar to last week, we see that the nectar flow is going on strong, with the largest hives gaining around 15 pounds in just 5 days! However, those 5 days were not prime foraging weather with intermittent rain and cloudy skies during the week. This weekend’s cooler temperatures and persistent rainfall clearly halted honey production with the weight gain largely flat lining from the afternoon on April 22nd all the way through the 25th. This can clearly be seen in Wake-Ref1 and Orange-Ref2 in the “greater than 130 lbs” group and Orange-1 and Wilson-1 in the “85-130 lbs” group.

Next week, we will take a deeper dive into how the rain has affected the nectar flow and compare the patterns in weight gain the week before, the week during, and the week after an extended period of rainfall!

Week 2

This week, we have data from 25 hive scales from April 11-April 18th. I’ve chosen to group the hives into four different weight classes for this week: 1) Less than 50 lbs., 2) 50-75 lbs., 3) 75-100 lbs., 4) More than 100 lbs. These weight classes aren’t fixed, so hives are likely to change weight class each week as well as the cut offs for these classes, especially as the nectar flow progresses.  I also “cleaned up” the data by removing weights taken when beekeepers were in their hives. My intention with the first week’s post was to show how messy this data can be and how we will have to “clean up” the data by removing some readings when the hive is being inspected or manipulated. We are still looking at the best way to account for supplemental feedings but we won’t worry about doing that until we are looking at several months’ worth of data!

So, let’s see what’s going on:

week 2 - Greater than 100 lbs 

week 2 - 75-100 lbs

week 2 - 50-75 lbs

week 2 - Less than 50 lbs 

I want to take a minute to walk through how I interpret the data. So first off, I like to look at overall trends: what was the weight at the beginning of the week vs. the weight at the end of the week. In doing so,  I look for hives that have added equipment which are easy to spot with a dramatic increase in weight , roughly 10-15 lbs, in 15 minutes.  For those hives, I look at the trend before and after the equipment was added to assess what’s going on. So for Wake-2 in the >100 lbs. weight class, you can see on April 15th that beekeeper added equipment and the hive has been remained steady ever since.  But in the case of Wilson-1 in the 75-100 lbs. weight class, after the equipment was added on April 13th, the hive has continued to put on weight in honey stores.

Another thing I immediately look for is evidence of supplemental feeding. A great example of supplemental feeding is shown by Nash-1 in the 75-100 lbs. weight class. There is a clear spike of ~15 lbs on the 11th but unlike hives where folks have added equipment, you see the weight drop by 10 lbs over the next 5 days. Added equipment shows a large jump in the weight within 15 minutes but the weight readings after that do not lose that same magnitude of weight. Whereas with supplemental feedings, the weight will continually drop as the bees consume and expel that sugar water for energy or brood rearing.  Other examples of supplemental feeding can be seen in week 1 in the graph of just Wake county hives,Wake-2 and Wake-4, with big jumps in the weight followed by a steady decline as those resources are used.

This week, I heard several reports of tulip poplar and black locust in bloom and looking at the weight gains this week, it looks like bees are making use of both of these great nectar sources! As I sorted the hives out into these weight classes, it became apparent that the size of the hive plays a role in how well they are able to capitalize on a food resource. In the greater than  100 lbs. weight class, you can see Wake-3, Wake-4, and Wake-Ref1 are tracking almost identically, each gaining 15-20 lbs just this week! In the 75-100 lbs class, Orange-1 and Wilson-1 have gained about 10 lbs this week (when  the weight gain caused by the added equipment for Wilson-1 is removed) and Wake-5 gaining closer to 15 lbs (when  the weight of the brick they added on the 17th is subtracted). In the 50-75 lbs. weight class, the data shows  a ~5 lbs weight gain for Orange-2 and Durham-1 and then less than a 5 lb. weight gain for Durham-2 and Durham-3 in the less than 50 lb. weight class. This trend would certainly make sense since the more bees in a hive, the more foragers they have to capitalize on a resource.

I only singled out the hives showing a clear weight gain throughout the whole week time span. However, there is still a lot of variability across regions and across weight classes that will hopefully become clearer as the flow continues! In general, most hives are starting to put on weight, especially those in the higher weight classes. Keep an eye out for tulip poplar and black locust blooming in your area!

Week 1

Almost all of our beekeepers have their scales set up now and we are ready to start diving into the data. Currently, we have 17 hive scales that have been active from April 1-April 11 that we can take a look at this week, and next week, we will hopefully be able to report on all 34!

hive scale in wake country

So as you can see, the data is very noisy…we will work on figuring out how best to display the data from all 34 locations without oversimplifying it or transforming the data too much. But just looking at the weight on April 1st and the weight on April 11th for all of these hives, I see relatively little change in weight. There might be a slight increase going on but to me, it is not strong enough to indicate the poplar flow has started.

There are several folks supplementally feeding quite frequently and as a result, these hives appear to be building up, again comparing the weight from the 1st to the 11th. Now looking at hives that have not been fed so frequently, it appears there is just enough forage to sustain colonies but not enough to start packing the honey on.

If you’re wondering about the data gaps for some of the scales, I removed any weight readings that were taken when hives were strapped down during the storm we had this past week. With the inclement weather and high winds, some folks strapped their hives to the scales to stabilize them (the mechanism these scales use to take the weight can cause the hive to get a little wobbly). This created elevated readings from the pressure of the ratchet straps so to simplify the graph, I went ahead and removed these readings.

Now since we have 7 scales up in Wake county, let’s take a deeper dive into what’s going on there:

hive scale in wake country - April 1-April 11

Looking at these 7 scales, I’ll be honest, it’s hard to tell what’s going on with only 10  days of weight data.  Wake-1, 6, and Ref1 appear rather flat, in fact 1 and 6 are even declining slightly. Since these are not being supplementally fed, it leads me to believe we are still waiting for the poplars to pop! Wake-2, 3, 4 and 5 are being fed fairly regularly and are starting to put that food to use, gaining ~20 pounds or in the case of Wake-2 burning through 20 pounds in a short amount of time. Wake-4 is an extreme example of this, gaining almost 30 pounds from April 1 to April 11!

Tulip poplar shouldn’t be too far out and several folks have mentioned they’ve already seen some starting to bloom! We will continue to work with this data and try to find the best way to display it from twice as many hives next week! Yowza!

Week 0

The project is finally underway! We have 32 scales out so far with a few more getting set up this next week! We will follow hives county by county through the course of the project and report the weekly weight data here. We will post the first week’s data starting week 1 in the format seen below, and then as we get more data over the next few weeks we will build out the graph at the bottom of the page and get a better idea of what the bees are up to!

March 28th - April 4th

I wish we could have gotten scales out sooner to capture what’s been going on with this wacky weather but fortunately we have had scales out at the Bayer Bee Care Center apiary since July! Here’s what they’ve been up to in 2017:

January 1 - March 20, 2017

Special Features

Each week, I get a chance to see what the bees have been up to and how they are responding to their environment through the weight data. As I compile the data and start trying to interpret it, I find new topics to explore and new questions to ask. So as these questions arise, I will take a deeper dive into the data in this special feature section! I will pull in other data sets and set up side experiments to try and better understand drivers of weight change. In doing so, I hope to provide greater insight into how folks can use weight data to better understand their hive.

What is an electronic hive scale?

It’s a battery operated scale that measures the weight of the hive. The Solutionbee scales involved in this project take weight readings every 15 minutes, although there are many other scale models and some that read and transmit the data in real time. Just google “hive scale” to see all of the different groups offering this kind of technology!

What insight can a scale provide?

Hive weight data can show a countless number of activities in the hive and as more people start working with this technology, the more we will learn! So far, we’ve been able to see swarm events, robbing, nectar processing and nectar flows.

Why is Bayer interested in hive scales?

We acknowledge there are many factors affecting bee health, with nutrition playing a major role. This information will provide a better idea of what floral resources are available for sustaining healthy hives in the local areas and how best to work with unique landscapes to alleviate the stress of limited forage.

Hasn’t this already been done?

We fully acknowledge the efforts of many other groups who have worked extensively with scale data (go to and to see some long term national level scale data). With this project, we hope to provide local beekeepers with the tools to assess the nectar landscape in their own backyard.

What will Bayer do with the data and how will we receive updates?

We will post reports of the weight data on a weekly basis throughout the active season into early October. After the bees begin to wind down for winter, we will put together a comprehensive report using the GIS data and share it on this page. We will then bring in all of the participating beekeepers and decide how best to move forward with the project and provide monthly updates throughout the winter.

Why is Bayer interested in bee health?

Bayer is interested in finding solutions to increase yields and protect pollinators which are critical to food production and agricultural sustainability. For nearly 30 years, Bayer has been committed to environmental stewardship and the protection of beneficial insects and bees. By funding grants for bee health research, exploring new chemistries for potential miticides, and engaging in outreach and education, we strive to protect the health of both honey bees and native bees. In addition to general bee health research initiatives, as part of our commitment to environmental stewardship, all of the chemicals we develop go through rigorous bee toxicity testing to ensure that when our products are used properly, they pose little risk to insect pollinators.
