Female Dolophilodes distinctus (Tiny Black Gold Speckled-Winged Caddis) Caddisfly Adult
View 6 PicturesThis is a really strange specimen. I would guess it's one of the dry caddis pupa that scoots across the surface of the water as a pupa rather than emerging right away. Its "wing pads (
Wing pad: A protrusion from the thorax of an insect nymph which holds the developing wings. Black wing pads usually indicate that the nymph is nearly ready to emerge into an adult.)" sure don't look right, though. Maybe they're deformed and that's why I was able to find this one as a pupa in the first place. It also looks like it might be a caddis adult missing its wings, but since I found three of them, that kind of rules out such an anomalous maiming.
The wing pads on this final instar Baetidae
mayfly nymph are extremely dark.
I found this one and one other on a midstream rock. The previous day, I caught a similar creature kicking around on the water's surface.
This one died and shriveled a little bit before I could photograph it, but it's basically in its original shape.
