Male Dolophilodes distinctus (Tiny Black Gold Speckled-Winged Caddis) Caddisfly AdultMale Dolophilodes distinctus (Tiny Black Gold Speckled-Winged Caddis) Caddisfly Adult View 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).

Hydropsyche californica (Spotted Sedge) Caddisfly LarvaHydropsyche californica (Spotted Sedge) Caddisfly Larva View 5 PicturesSize - 14 mm

Condition - preserved

Habitat - cobble bottom, moderate flow run, at a depth of approx. 1 1/2 feet.

Key Characters - pair of large prosternal sclerites (Sclerite: A hard plate of chitinous material, such as those that form the exoskeletons of arthropods, uninterrupted by cracks or sutures.)


This is a very common taxon at this location. I collected using a kick net. In life, it is bright olive green ventrally, shading to a dull olive at its dorsal (Dorsal: Top.) abdominal surfaces. In the hand, the legs, thoraxic regions, and head appear medium chocolate brown. The stark contrast of the thoraxic plate's dark edges and light legs are effects of preserving. The plumouse anal hooks were duck down gray, not the color of the gills as appears in the preserved specimen.

The Lower Yuba River is a good habitat for this species, being a larger river with an open canopy. The Feather River just to the north of the Yuba system also finds H. californica in abundance. The other common Hydropsyche species in the area, Hydropsyche occidentalis, seems to prefer smaller, shaded streams.

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

)
" 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.
