I just can't convince myself that either of the larvae pictured in this section are Brachycentridae. The cases don't conform to any I know (usually tapered four-sided "log cabin" cases for most Brachycentrus or smaller tapered round cases for Micrasema and Amiocentrus).

You're probably right. These larvae were from the old site and I mostly had identifications based on various helpful emails I've since lost track of. So I don't remember what the rationale was.

That's why the new site has this comment system on the specimens: to keep a public record of the identification talk.

This is another specimen that has bothered me for some time. The fourth picture in the sequence seems to show a dorsal hump. I'm guessing that this is another limnephilid. Creno, help me out here!

Gonzo - Sorry I cannot help much other than agree with you it is not a brachycentrid. Looks like a limnephilid to me. I can't get a good enough view of gills or legs to get any closer.

Fair enough. Thanks, Dave.
