These are glossosomatids, Jason. They are probably Glossosoma nigrior, though it is possible that we are looking at mixed species. The ones to the right with their aggregate of similar sized grains are classic Glossosoma, while the ones to the left with the large anchor pebbles could possibly be Agapetus. Regardless, they're all commonly referred to as saddle case makers. In this picture: Caddisfly Family Glossosomatidae (Little Black Caddisfly). From Spring Creek in Wisconsin.

just wanted to spread the word about agapetus. many trout streams have healthy populations of agapetus and there is no reason that some of these species are important to early season emerger/dry fly fishing. small (#18-22) black caddis dry or emerger patterns will mimic them nicely, as well as Dolophilodes Wormaldia and Chimarra.

my colleagues are describing 12 new species of agapetus, mostly from the southeastern united states. i would encourage troutnuts to attempt to collect and rear agapetus pupae. it is pretty easy to do, find pupating cases and remove them from the rocks using forceps and into a small jar of water. If you use a jar with a small amount of water (just a little bit more than required to cover the pupae, removing the small stones around the puparium), then they will pupate in a refrigerator (preferably 60 C or so). Leave the lid loose to allow oxygen to equilibrate with the pupae. This also works for Rhyacophila, which build a similar puparium. We are describing new species of both Agapetus and Rhyacophila and it would be great to have specimens from Troutnuts!!! if interested in doing this, and it is time, email me litobrancha@yahoo.com You can send them to me in alcohol, who knows what else is out there!!!!
