Posts: 17Find a used copy of Wiggin's "trichoptera larvae of north america" or some similar title. It is the best guide to get to genus for all the caddis you may run across

Hi Earl (and John),

Earl, I'm assuming that you're referring to my tentative guess that this might be Pycnopsyche. Actually, it's not that I'm not aware of the more comprehensive keys or where to find them, it's just that I rarely have more than bits and pieces (along with my own experience) to call upon on the spur of the moment. I usually won't comment on a specimen if I'm not pretty sure that it's something I'm familiar with. And I realize that my methods are not scientific.

However, Limnephilids always drive me a little crazy. If you have the Wiggins keys on hand, I'd be interested to know what you can make of this specimen.

Your right, this specimen is Pycnopsyche sp. The key characters that can lead you there are all visible in the above photos. Abdominal gills are single; there is an elongate sclerite posterior to the lateral hump that can be seen in one of the photos; and finally the metanotal sa1 sclerites are not fused on the mid-dorsal line. The case is also fairly characteristic of Pycnopsyche. The only genus that is really confusable is Hydatophylax sp., but in most cases the metanotal sa1 sclerites are fused on that bug.

Those are the characters, but the fact is it just looks like Pycnopsyche.

Hope that helps.

Earl
