The Specimen

Rheotanytarsus Midge LarvaRheotanytarsus  Midge Larva View 6 PicturesThis peculiar midge lived in a case tightly fixed to a rock, with several others of its kind. The case seems to be made of tiny grains of sand. I'm not sure what the function is for the little lines sticking out the front, because they aren't legs.

I have a small tank with some of these on the rocks and noticed the midges coming out and cleaning the lines so I talked to my stream ecology professor and he told me I have rheotanytarsus and along those lines there are small lines of silk that they use to collect food just in case anyone was still wondering.

Welcome to the forum, Mike! Thanks for the info. One of the great things about this site is that your post is linked to the specimen for future reference. Are you majoring in biology?
