Phylocentropus carolinus

Dave was correct in his suspicion.

Thanks Dave

I didn't look close enough at the genus name other than it was long and began with a P. It's a new family for the guide, and it figures the only angle I didn't photograph was the back of the legs:-)

leg photos

don't worry about it as that is the only genus I can think of where a posterior hind tarsal photo would be very useful. It seems every critter has a different feature that makes ids easier. that is why, at least for most caddis, ids from photos are so problematic. But yours are better than most :)

Phylocentropus

Tom - it is Dipseudopsidae: Phylocentropus not Polycentropodidae: Polycentropus

posterior side of hind tibia

if you can get a good posterior view of the hind tibia we may be able to tell you which species. I can see enough in the above photo to guess P. carolinus but can't really be sure. Otherwise Don should be able to see the spines/shape easily with the scope and figure it out.

Alas,

only lucidus and placidus are known from our area to the best of my knowledge, and I don't know of a key to separate the larvae. If you do!! please let me know, and I will give it a go.
Thanks.

Northeastern Phylocentropus

Don - I have seen P.carolinus from New Brunswick, Maine, and New York. I am aware of published records from several other states/provinces in the northeast. Larval descriptions were recently prepared for the three "common" species (Skurkie & Morse 1998, Insecta Mundi 12(3-4):175-179) and should work if ya stay in the NE. Fairly obscure journal so let me know if you can't get a copy.

Thanks. I actually am a member of the society that produces Insecta Mundi, and in checking the database of our collection library it seems I pulled out the paper from the issue (all paper then) and promptly forgot about it once it was numbered and placed into the collection library.

I will pursue this further. It is a very nice specimen, and I have only seen adults (from lights) before. I will also check our adult Phylocentropus for any carolina that may have snuck in, though I think John Weaver has checked at least most of our specimens of that group and a number of families, especially Lepidostomatidae.
