Goodbye to the bees for now!

This summer we spent over 80 hours watching bees. Which, if you haven’t ever done that, I highly recommend it. Ok, maybe you don’t need to spend quite that much time bee watching. But I promise that even spending just a few minutes will be both entertaining and rejuvenating.

We saw wool-carder bees chase bumble bees, chase each other, and even find love (ok, “mate”).


Likewise, the bumble bees were busy doing what they do – collecting food (pollen and nectar), both gracefully and not so gracefully (they are called “bumble” for a reason).


And among all this fun, we even collected lots of data. Data analysis is ongoing, but results are looking very strong in support of our hypothesis – that wool-carder bees are bad news for bumble bees. Wool-carders kept bumbles away from flowers through direct attacks, and competition. And preliminary data suggests wool-carders are bad for the flowers they visit too.

So, as the weather turns colder, and the bees all start to disappear, I’ll be busy analyzing results and planning more research projects! And of course I’ll keep you all informed of any publications (both scientific and for the general public) that come from this research.

I can’t thank you all enough for making this field season such a success. I couldn’t have completed this summer’s research without you. I’m truly, truly grateful.

About This Project

Is a recently introduced invasive species, the European wool-carder bee, threatening our native bumble bees?

Male wool-carder bees use evolved weapons on the base of their abdomen to ram into bumble bees trying to gain access to flowers. This project will determine if these interactions are hurting bumble bee lifetime reproductive success.

Blast off!
