Apatania (Early Smoky Wing Sedges) Caddisfly AdultApatania (Early Smoky Wing Sedges) Caddisfly Adult View 7 PicturesThis one actually had a medium tan body when it emerged. By the time I took the picture it was dark as night. I was actually looking through my box of specimens trying to figure out where that tan one I caught disappeared to. Then I realized this is it.

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.

Lepidostoma (Little Brown Sedges) Little Brown Sedge LarvaLepidostoma (Little Brown Sedges) Little Brown Sedge Larva View 6 PicturesThis one got a little bit damaged in the abdomen when I extracted it from its case. That's a delicate job.

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).
