The Taxa List for Buck Mt. Creek

Another gray day after 2-3 more inches of rain.  Still, I thought I'd see what I could find at Buck Mt. Creek.  What I found was high water and, consequently, not a whole lot of insects.  Perlesta common stoneflies in collections of leaves and twigs including the one at the top of the page and the one in the photo below.

Oh yes, some flatheaded mayflies (probably M. modestum), a couple of spiny crawlers (Eurylophella verisimilis), and one "baby giant," a small, immature Giant stonefly.   When they're this small, there's no way to do species ID.

While we wait for the water to drop, I thought I'd post a list I've assembled of the taxa I've found in Buck Mt. Creek.  I've mentioned before that I think this is one of the richest streams I explore -- in terms of the variety of insects calling it home.  Local readers should find this of interest.
