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.

Hydropsyche aenigma (Spotted Sedge) Caddisfly AdultHydropsyche aenigma (Spotted Sedge) Caddisfly Adult View 18 PicturesThese big caddisflies were tempting trout as they wriggled out of their shucks (
Here's an underwater view of the pupal shucks of several already-emerged Brachycentrus numerosus caddisflies.

Shuck: The shed exoskeleton left over when an insect molts into its next stage or instar. Most often it describes the last nymphal or pupal skin exited during emergence into a winged adult.

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.

Brachycentrus (Grannoms) Caddisfly PupaBrachycentrus (Grannoms) Caddisfly Pupa View 10 PicturesThe green blob contained in this case is a pupa in the early stages of transformation from larva to the final stage we generally picture and imitate. This specimen and several like it were fixed to a rock I picked up, and each one had the front of its case sealed off, protecting the helpless pupa from predation. It's neat to see the insect part-way through such a radical transformation.

It was very hard to extract this thing from its case, so there's a bit of extra goo near the head from where I accidentally punctured it.

Cheumatopsyche (Little Sister Sedges) Caddisfly PupaCheumatopsyche (Little Sister Sedges) Caddisfly Pupa View 10 PicturesThis is the first fully formed caddis pupa (technically, a pharate adult (Pharate adult: Caddisflies are considered to be pupae during their transformation from larva into adult. This transformation is complete before they're ready to emerge. The emerging insect we imitate with the "pupa" patterns we tie is technically called a pharate adult. It is a fully-formed adult caddisfly with one extra layer of exoskeleton surrounding it and restricting its wings.)) that I've collected and photographed alive and healthy. I'll put a video of this specimen online soon, too.
