Emergence and egg-laying behaviors vary widely within this family of net-spinning caddisflies. Some species, like Dolophilodes distinctus, have very unusual quirks. That species and Chimarra aterrima are two of the most important in this family.

Dolophilodes distinctus (Tiny Black Gold Speckled-Winged Caddis) Caddisfly AdultDolophilodes distinctus (Tiny Black Gold Speckled-Winged Caddis) Caddisfly AdultView 6 PicturesThis caddis species was dancing high over the stream, spaced a foot or two apart across most of its width, very much like Ephemera mayfly spinners but with more side-to-side motion mixed in. There were more than enough to get the trout interested, but I wasn't able to stick around until they fell on the water (if they did at all).

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 (

" 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.

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.

Pupa color? 5 Replies »

Seems like dead drifting the pupa pattern during the emergence time is a good way to fish this before the adults are on the water.

Does the pupa retain the orange color of the larva or do they have the color of the adult?
