I observed an interaction between crane flies and June beetles that puzzled me. I don’t know if this is unusual but I’ve never seen it or heard about it.
Craneflies are swarming right now. Last night they were buzzing around the large beetles like in this photo. This happened more than once, with various sized craneflies and different beetles. Then a cranefly would land on the beetle for a while, flit around and crawl all over the beetle, settle back down, and repeat. If I scared one away, it—or one like it—quickly returned.
Does anyone have an explanation for this behavior?
