Plectrocnemia missing

Posted by AndyV on Aug 25, 2022

I believe this is missing from the list. Unsure of it's importance. However, they was a study on Plectrocnemia conspersa relative to trout populations in Ashdown Forest streams [Schofield et al. (1988)].

The first image is of a live caddis. It was collected from Trout Creek which is in the Delaware River watershed in upstate NY. The background is 1/4 inch ruled graph paper which is under the Petrie dish holding the caddis with water.

The second shows small silk nets found on rocks in the same stream during the same sampling.

I've been working all of my ID books including "Freshwater Macroinvertebrates of Northeastern North America" by Peckarsky.

The upper lip does not seem to have the T shape of a Fingernet caddis. It does have the heavy mandible with a brush of Polycentropodidae.

But, I'm not completely satisfied.

Anyone have thoughts on this?
