When I decided to plant a veggie garden this year, I had no idea it would create a habitat that would draw such an interesting variety of insects. One of the biggest surprises was this bee:
Googling around, I learned that it is a squash bee, which specializes in pollinating squashes and cucumbers. Two things about this bee fascinate me. First, how in the heck did it find my squashes? It’s not like there are tons of veggie gardens near me. Second, what is that drop of liquid between its eyes?
I don’t know if I’ll ever understand the answer to the first question. But I found a blog about pollinators written by a grad student, Athena, who studies bumble bee foraging ecology, and she answered the second question for me here. It turns out what I thought was a drop of liquid was an illusion. The bright lemon yellow patch you see just in front of the antennae is part of the bee’s exoskeleton, and they have a little bump there.
I was interpreting the yellow patch as highlights from the squash blossom reflecting in liquid. The illusion was compounded by the fact that it’s easy to think the bump is a drop of liquid if you’re already thinking along those lines, and if you think of the dark areas in between the eyes, which make a rather circular pattern, as shadows at the edges of the drop.
By the way, Athena also told me that only males have that yellow patch. Now I’m curious as to whether it’s used to attract females or compete with other males. So many questions about one tiny little bee! I’m definitely planting butternut squash again next year and keeping my eyes out for these guys.
In addition to bees in my garden, there are little brown butterflies, which I’ve never seen before. I presume they’re feeding on pollen and/or nectar as well:
And, of course, the insects that are drawn to my garden have their own predators, in the form of dragonflies:
I’ve always felt good that I have a couple of small plots of native wildflowers in my yard. I put those in specifically to provide habitat for native animals (although the Japanese beetles are helping themselves as well, darn them!). It never occurred to me that I could do so much by planting food for myself. Definitely a bonus, not to mention the cheap entertainment I get from watching and photographing all of these critters. Plus, I’m learning new things. This is definitely a project that has paid for itself!
