Neophylax (Autumn Mottled Sedges) Caddisfly LarvaNeophylax (Autumn Mottled Sedges) Caddisfly Larva View 11 PicturesI haven't really had time to ID this one; I'm just tentatively guessing based on the case that it's in Glossosomatidae.

Male Mystacides sepulchralis (Black Dancer) Caddisfly AdultMale Mystacides sepulchralis (Black Dancer) Caddisfly Adult View 10 PicturesThis was one of many of its species which were gathered in small, low-flying swarms of about a dozen insects near the alder trees in the afternoon on a small stream.

Phryganeidae Caddisfly LarvaPhryganeidae Caddisfly Larva View 5 PicturesThis "specimen" is actually two caddis larvae fighting each other over a case. The case is a hollow tube; one larva would go in the back end, presumably bite the other, and chase it out. The invader crawled forward into the case while the other one fled, and then it went around to the back and bit the first one. They did this several times, and I recorded it on video.

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.

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).
