Caddisfly Genus Hydatophylax

These are often called Giant Cream Pattern-Wing Sedges.

These are huge caddisflies. The larvae may be nearly an inch and a half long and build three-inch cases. Hook sizes 4-6 are appropriate for the pupae.

Jargon Defined:

Larvae: 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.

Pupae: 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.
