A caddis larva, order Trichoptera, that was caught in a hand net in river margins, emerging from its case that has largely been made from twigs, bark and aquatic mollusc shells. The larva can be seen emerging from the case in the picture. The caddis larva, also called a sedge, constructs a protective, camouflaged case from any items it can find such as bark, twigs and water snail shells as well as grit and any other materials it can find. It then pupates and emerges from the water as an adult fly. Caddis larva can be found in lakes, ponds, rivers and streams and in the UK there are about 200 different species. Caddis fly larva, and the adult flies, are eaten by fish and trout anglers use artificial flies that imitate both the larvae and the flies to catch trout. This caddis larva was found in the Dorset Stour river. Photographed on a white background. Dorset England UK GB
