Johnny -

I don't have any idea what your adult caddis is but the larvae look like they could be early instar Dicosmoecus gilvipes. Here are some photos.

Where were these collected - the larvae also look like some of the eastern Pycnopsyche species. Also how large are the larvae? The adult is not a caddis, the antennae are too short for something that size. It is one of the megalotera.

The larvae (approx. 1"-2" with dark brown/black heads and what appeared to be lighter, cream-colored abdomens) were collected from submerged boulders along the banks of the river as well as on rocks positioned between the seams of faster and slower moving water. Any more input or helpful advice and information would be/is greatly appreciated.

Sorry, poorly worded question on my part. What Country/State/Province were these collected in? If I presume CA from your response on the Megaloptera The middle larvae doesn't look as burly as the other two so if may be a species of Psychoglypha.

Dave-

I believe it to be the Giant Lacewing, Polystoechotes punctata.

Great job on the ID, Roger. The lack of mandibles precluded the fishflies and I wasn't figuring lacewings over its size.
