Neophylax (Autumn Mottled Sedges) Caddisfly Larva

View 7 PicturesThe size of the head compared to the body in this larva is surprising, and I think this means it's a fairly early instar (Instar: Many invertebrates molt through dozens of progressively larger and better-developed stages as they grow. Each of these stages is known as an instar. Hard-bodied nymphs typically molt through more instars than soft-bodied larvae.) of something which is going to get a lot bigger, but I'm not sure.

Cheumatopsyche (Little Sister Sedges) Caddisfly Pupa

View 3 PicturesI was surprised how bright green this pupa is. It's chartreuse. After collecting it, I experimented with melting down chartreuse jigs and making little translucent rubber caddis abdomens on my flies. They looked good, and the trout liked them, but they weren't very durable at all. This specimen is recently deceased in the photographs.

Brachycentrus americanus (American Grannom) Caddisfly Larva

View 13 PicturesBoth the genus ID (Merritt & Cummins) and species ID (Flint 1984) are pretty confident for this larva, a nice example of a common western caddisfly. It was by far the most abundant insect in my kicknet sample on this trip, and many of the rocks in the fast riffle where I sampled had dozens of these larvae clinging on.

Hydropsychidae Caddisfly Larva

View 5 PicturesThis is one of the most vividly green Hydropsychidae larvae I've caught.

Helicopsyche borealis (Speckled Peter) Caddisfly Adult

View 7 PicturesThis one keys pretty easily to the Helicopsychidae family, of which there is only one genus in North America, and one species reported in this general area.

Mystacides sepulchralis (Black Dancer) Caddisfly Adult

View 3 PicturesI captured this small caddisfly from one of many dense mating swarms under overhanging alder trees in a slow stretch of the river. There were localized rises of trout under the swarms.

Male Hydropsyche (Spotted Sedges) Caddisfly Adult

View 5 PicturesThis was identified by Dave Ruiter as Hydropsyche californica or Hydropsyche occidentalis, but the characteristics were not clear enough to tell them apart.

Jargon Defined:

Abdomens: The rear and usually the longest (ten-segmented in mayflies) portion of an insect's body, to which the tails are attached.

Instar: Many invertebrates molt through dozens of progressively larger and better-developed stages as they grow. Each of these stages is known as an instar. Hard-bodied nymphs typically molt through more instars than soft-bodied larvae.

Larva: Many classes of aquatic insects, such as caddisflies, midges, craneflies, dobsonflies, alderflies, and many more, are known as "larvae" rather than "nymphs" in their juvenile stages. They have mostly soft bodies rather than hard exoskeletons. These insects also advance through a "pupa" stage before reaching adulthood.

Pupa: Any insect which spends most of its juvenile lifetime as a larva first becomes a pupa for a time before emerging as a fully grown adult. Depending on the species, the pupal form can be very important for fly fishermen to imitate.
