Hi all,
It's the time of year when a particular wetland stonefly species starts its adult emergence. The species is a small one called Ostrocerca dimicki. The adults are just about 5mm long. I've attached a photo of some of the adults I caught in a small container. It's easiest to find these little guys near the tiny flowing water channel at the southwest part of the boardwalk loop. The adults are probably all over in the vegetation near the channel, but I mainly see them on the white-painted posts that support the interpretive sign there. I most often see them on warm, sunny days.
I also saw some mature nymphs of these stoneflies on vegetation in some of the gently flowing areas of the channel. I used my submersible camera to try to photograph them, but they kept trying to move out of my view. Here are a couple sketchy photos. Hopefully I'll get to take some better ones later.
Cheers,
Bill
