I 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.

This caddisfly was collected from the Long Lake Branch of the White River on June 5th, 2005 and added to Troutnut.com on May 25th, 2006.

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.

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.
