This common name refers to only one genus.

Caddisfly Genus Psychoglypha

These are often called Snow Sedges.
These caddisflies may be important to the winter angler because they are one of the only insects around. Gary LaFontaine relays an interesting correspondence about this genus in Caddisflies:

Dr. George Roemhild explained to me how he finds these winter caddisflies in February and March: "They crawl up on the snowbanks, but when the sun hits their dark wings they melt down out of sight. That's how I collect them, by walking along looking for holes in the snow."

I will keep an eye out this winter and hopefully collect some specimens to photograph.
Male Psychoglypha (Snow Sedges) Caddisfly AdultMale Psychoglypha (Snow Sedges) Caddisfly Adult View 2 PicturesThis Psychoglypha adult was found clinging to my garage door in the evening on April 9, 2013. It measures 21 mm in length, from the front of head to the end of wings. It is my hope that Creno will be able to identify it to species based on the image of its genitalia. However, if other images are required for a species ID, the specimen is available, so they can be easily taken. Thanks, Roger Rohrbeck, Mercer Island, WA.
