Hatching Behavior

Time Of Day (?): Slow water

The pupae take a long time to break through the film.

Egg-Laying Behavior

Females lay their eggs underwater, either by diving through the surface or crawling down streamside rocks and twigs.

Larva & Pupa Biology

Current Speed: Slow

Shelter Type: Unusual retreat; see notes

These caddisflies build unusual homes, which Gary LaFontaine describes in detail in Caddisflies:

The small, yellow-and-brown larvae of this genus builds a chamberlike retreat, open at both ends, over a hollow in a stick or rock. It leaves loose threads over each opening and when a smaller animal touches the retreat, disturbing the threads, this eight- to ten-millimeter carnivore rushes out and seizes its prey.

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.
