Found a couple of caddisflies on a rock.

I have never seen that many so well packed in.


That's what grannoms do. Maybe Creno can tell us why. I managed to grab 10 or 15 at once and the ones that didn't get away were all females but I don't know if that was just random. I did notice some crawling down the rock and then underwater. I'm assuming to lay eggs?

Did this just happen ???


The Brachycentrus sp. emergences here (South Central PA) start in the beginning of April.

Nice Eric...With us being behind you a bit weather wise, what do you think I'm tying up? :)

Sorry - I have never seen that and cannot find any literature that addresses it. Some Brachycentrus are known to pupate in masses, and males of some species often have very brief emergence periods, even a day or two. But that doesn't really explain why all the males would get together in a mass. They should be out wandering the neighborhood. Many caddis use pheromones to get the adults together. But if that mass was all females that wouldn't make much sense either. I am at a loss but great pics. May I use them to show other caddis folks? Maybe some one else has an idea what is going on.
