I collected these filled mason bee nesting tubes this morning to make room in tiny little House #4.
I set up House #4 last year as an afterthought and it has become a very happenin' place. It's like the dive bar of the Clayton Street bee scene.
This morning, nine of the tubes were sealed, so I carefully took them out while the temperature was still in the 40s and the bees were still sleeping inside. (Mason bees need the temperature to be above 54 degrees to fly.) I replaced the tubes with empty tubes, and brought the filled ones in to label them and store them in the garage. I even photographed them to show how proud I was of the bees' hard work.
However... One of the tubes wasn't actually sealed at all and still had a mama bee inside waiting to warm up and finish her nest. Ooops! When I saw her little antennae pop out the end while I was typing, I snapped a photo but she was shy and ducked back in.
Just another adventure in the life of Heather Harvey, native bee detective! But seriously, when we say mason bees are gentle bees - this is what we're talking about. I carried the tube back outside and put it back in the house. Mama and her brood are back where they belong with the other hipsters in House #4.
Here's what was happening at House #1 yesterday morning. When I counted the bees last night, there were 11 sleepy ladies guarding their brood. I hope to have some night video up soon.
"Ooooh! Look at that!" The very first reed Rita opened was completely filled with carefully-constructed egg chambers made of leaves. We were like kids at Christmas watching this beautiful work of nature unfold. This nest was created by a female leafcutter bee that used her mandibles to cut oval pieces of leaves, flew them back to the nest, and stuck them together with leaf sap and bee saliva to make a cozy chamber for her young to develop. She then filled each chamber with a loaf of pollen and laid an egg directly on that food source. The larvae hatched, ate the pollen, and each made a cocoon inside the chambers where they are currently developing into adult bees. If all goes well, eleven adult bees will hatch from these cocoons into Rita's garden sometime in late May or June.
Laurel and JJ also opened their nesting tubes and had mixed results. JJ had what appeared to be beneficial wasp larvae in some of her nesting tubes. She is going to isolate these nests so she can see what emerges in the spring or summer. Laurel found a couple of spiders nesting in the tubes, but no bees. It's not uncommon to have a small harvest the first year because there are so many variables involved. Nest location, light, temperature, timing, proximity to food sources, and just general bee preferences. Every bee is different and has specific likes and dislikes about potential nesting sites.
JJ shared a thoughtful insight about the all-female group's hardiness in the midst of the potential creepy crawlies just waiting to be uncovered when she said, "I think it's great that we are able to sit here and talk about all these worms and grubs and poop and nobody is screaming." In fact, there was zero screaming - only a bit of reasonable trepidation - as we finished with the tubes they brought from home and started opening the mason bee tubes from the nests that I manage. Mason bees provide for their young in the same manner as leafcutter bees, but instead of leaves they use mud to make their egg chambers.
The mason bee tubes tend to be messier to open because the larvae push feces and any leftover pollen out when they are spinning their cocoons, but seeing all of this detritus inside is also pretty interesting. Along with the cocoons we discovered a few pollen mites and parasitic wasp larvae, which are frequent hangers-on in native bee nests. We cleaned the cocoons by shaking them in some sand to remove these pests.
In the three chambers at top left you can see the yellow pollen loaves but no cocoons. Either the female didn't lay any eggs in these cells, or something caused them to die before consuming the pollen. To the right you can see the mud partitions separating each cocoon. The cocoons are silver, the black bits surrounding them are larva feces, and the yellow bits are leftover pollen. At bottom right is the crumbled mud cap the female created to seal the tube from predators.
Why do we harvest the bee cocoons? Native leafcutter and mason bees are snuggled up in their cocoons right now in your yard and they don't need our help to come out and do their important pollinating work this spring. But, by giving them boxes to nest in and bringing their cocoons in during the winter, we can help ensure their health and survival by: maintaining their temperature if we have a warm winter; keeping them safe from hungry birds; checking for pests and chalkbrood; and sharing them with others to promote the "keeping" of native bees. With as much as 40% of the world's bee population facing threats to its survival, this little bit we can do for the bees in our neighborhood can really add up.
Besides, it's fun to learn something new, as we discovered at the Bee Harvest Party. And it was fun to learn from each other. The ladies traded tips about building nesting houses and the best places to install them in their gardens. They even decided that, like the female bees, they had a preference for one type of nesting tube over another. There was also a glimpse of the empowerment that can happen when a group of women take on a new project. One of the guests admitted that her husband usually does the handy work around the house, but it was important to her to build her own bee house. This was a project she wanted to do, from start to finish, on her own. She not only finished it but she brought it to the party to share her design ideas.
At the end of the party, everyone took home the cocoons they harvested to increase their own native bee communities. They will keep them sheltered in a cool garage or the refrigerator until mid-March when the maple trees bloom and the bees will have a plentiful food source.
I am so appreciative of these ladies coming out on Sunday to share their interest in bees and ideas for aiding their survival. If you or your organization are interested in learning more about native pollinators and hosting your own bee education event, please contact me at firstname.lastname@example.org
These cute little males emerged in late March when I was sorting cocoons to put outside in the nesting house. The antenna preening is my favorite part.
That's the last bee pun, I promise!
Welcome to the blog for my new enterprise, BeesGoneWild! It's a business that lets me share my interest in and love of pollinators - specifically gentle, solitary bees - with other interested people and gives me an excuse to stand outside for hours and watch my gardens. BeesGoneWild started out as the Indiana Pollinator Project, an outreach effort I created in partnership with the Montessori School of Greater Lafayette. When I left the Montessori school in May, I still had all the contacts and the resources from the Pollinator Project, but no longer had the non-profit affiliation. So I started BeesGoneWild. I plan to continue to support the people who got started with native bees through our West Lafayette farmers market booth and invite new native beekeepers into the fold.
My primary focus is education and outreach to show people what bees do, why they are important to our food supply, and how we can help ensure their survival. I host native bee workshops for a small registration fee and I also sell nesting supplies and educational materials at farmers markets and through this website. Please send me an email if you share my interest in pollinators or check out my calendar on the events page and visit me at an upcoming event.
