This topic is about the Caddisfly Family Glossosomatidae

This family is one of the primitive caddisflies of the Rhyacophiloidea superfamily. However, they are not free-living like their better known cousins the Rhyacophilidae (Green Rockworm). Instead they build rounded "turtle" shaped cases that do not surround the larvae but are rather attached to the rock surface at their margins. Underneath is a sling made of secretions upon which the larvae ride, hence the common name Saddle-case Makers. There are four genera of possible interest but only one is generally recognized as important to anglers. See Glossosoma (Little Brown Short-horned Caddis) for details. The other three are so tiny that they are also called Pseudo-microcaddis.

Protoptila (Tiny Spotted Short-horned Caddis) is rarely important in trout streams and is generally found in warmer, larger water than the other two genera.

Agapetus (Tiny black Short-horned Caddis) is quite common in many northern streams.

Matrioptila is an extremely tiny southern genus.

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 You can send them to me in alcohol, who knows what else is out there!!!!

Great, Lito, another genus to add to my tying list--just what I needed! :) Just kidding pal, it's great to hear from you again! And I'll be on the lookout for Agapetus! (Actually, if Chimarra/Dolophilodes imitations work, I'm all set.) ;)
