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.

Baetidae (Blue-Winged Olives) Mayfly Nymph

It's got dark bands on the tail at the middle and tip, a rounded, oval 7th gill, and gill veinlets (Veinlet: Short insect wing veins connecting the major longitudinal veins to the wing margin.) which are visible but not conspicuous.

Arctopsyche grandis (Great Gray Spotted Sedge) Caddisfly Larva

View 14 PicturesAt first I had trouble believing this giant Hydropsychidae larva was actually a member of its family, because of the size. I had never seen such a thing. It turned out to be a member of this exceptionally large species with a fitting name, grandis.

Jargon Defined:

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.

Nymph: The juvenile, underwater stages of mayflies, stoneflies, dragonflies, and damselflies and other aquatic insects whose juvenile stages are covered by hard exoskeletons. The word can also refer to the fishing flies which imitate these creatures, in which case it is used as a blanket term for flies imitating any underwater stage of an invertebrate (except for crayfish and leeches).

Veinlets: Short insect wing veins connecting the major longitudinal veins to the wing margin.
