Posts: 17	This one looks like an almost ready to emerge male Baetis sp., but I can't be 100% based on the pictures and I definitely can't go any further than that. As a side note, if anyone is interested in a good key to the larvae of Baetidae, search google for "EPA photographic Baetidae key" and click on the PDF at the EPA site (direct link to the PDF here). The key has some good photos and works very well for the eastern U.S.
