Female Dolophilodes distinctus (Tiny Black Gold Speckled-Winged Caddis) Caddisfly Adult Pictures

Ross (1944) mentions that Dolophilodes (Trentonius) distinctus adults "...remarkable b/c of the production of adults during the entire year, incl. the winter months, and the wingless condition of most of the females.....records indicate the females produced during the colder months are all wingless.....Winged females have been taken during the warmer months of the year." He goes on to mention that wing presence is caused by temperature reactions influencing late larvae. Was it a really cold stream? Seems late for ambient air influences.

Ignoring the (perhaps deformed) wing pads, to me at least, the general body shape looks a lot more like a dragonfly nymph.
