I took a steam sample right near my house today, Quitty, and found 2 types of bugs. Lots of freshwater shrimp 14-16 and some other bug which I don’t know what it is. Maybe someone can help. They looked almost like small helgramittes, small thin body, black head, brown body, pinchers in front and something coming out the back. Is it possible they are helgramittes? they were size 10-12.
Under each thumbnail at photobucket,(on your screen, anyway), there are four little windows with various iterations of the URL for the photo. Cut and paste the SECOND one of the four, from the top, into here.
I tend to agree with JC on this, it would be fun to raise the insects and see what they become. However, as I’m no expert on entemology, I looked it up and found a great photo.
Looks like it could be a free living caddis like a Rhyacophila species. It’s strange how a small helgrammite can be so similar to a free living caddis. Maybe someone out there with some more entymological knowledge than I could post a method that could be used to distinguish the two species. The free living caddis are little predators too. If you do a Google search on Rhyacophils caddis, you will find alot of information and pictures that look alot like your mystery bug.
