Onocosmoecus (Great Late-Summer Sedges) Caddisfly Larva

Collected May 10, 2008 from the Chena River in Alaska

Brachycentrus appalachia (Apple Caddis) Caddisfly Adult

View 13 PicturesI captured this specimen in the same color as this photograph, during its egg-laying flight. The emergers are much lighter.

Neophylax (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 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.

Psilotreta labida (Dark Blue Sedge) Caddisfly Larva

Rhyacophila fuscula (Green Sedge) Caddisfly Larva

View 11 PicturesI collected this larva and several like it from the same stream and on the same day as this pupa. I suspect they're the same species.

Collected June 5, 2005 from the Long Lake Branch of the White River in Wisconsin

Rhyacophila (Green Sedges) Caddisfly Pupa

View 11 PicturesI collected this pupa and several like it from the same stream and on the same day as this larva. I suspect they're the same species. Every pupa I collected was in a brown casing like the one shown in one of the pictures below. I cut this pupa out of its case after a picture so you can see more details. It is close to but not fully developed.

Cheumatopsyche (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.

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.

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.

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.
