Saddle Case Makers

I don't have a picture of the larvae, however they essentially build small 'igloos' out of gravel, and clamp them onto rocks. They don't move around a whole lot, but fish are still able to snack on them by picking them off of the rocks. Imitations would be a bit tricky as they would involve epoxy, a heavy rock, and a lot of patience.

These are both glossoma, the one on the right (with the darker wingcase) is closer to hatching...

This adult were found in late spring (around May, as were the pupae above), but they are common throughout the spring and summer. Hence a small tan caddis imitation is a good bet on the McKenzie (& most other places)
