This large and rather fine caddis fly came to the moth trap on Friday night. I believe it is Stenophylax permistus (#730) as although there are similar species, it seems the most likely of the family to be found this early in the season. Stenophylax permistusm is a fairly common species with 2 generations, one in April-May and a second in July-August. This one must have been out and about a bit early. This species lives in temporary water in ditches and the like, where its nymphs make their shell out of dead leaves and vegetation.
