What they look like:
The Caddisfly Larva (plural – larvae) are worm-like with three pairs of well-developed legs on the first three body segments and hooks on the last one. Caddisflies are related to butterflies and moths.
Size:
Up to 20 mm long.
Where they live:
They live in a wide range of environments from fast flowing streams to freshwater ponds. Their soft bodies are usually covered in a protective silky case. They use the hooks at the end of their abdomen to hold on to their cases. Some species do not live in cases, using their hooks instead to cling to the stream bed and also to drag themselves backwards to escape from predators.
What they eat:
The Caddisfly Larva eats algae and plants (living and dead). Some species feed on other insects and spin silky nets to capture their prey. Some eat the larvae of other Caddisfly species, while others scrape algae from stones or plants, or shred leaf litter.
