A photograph of a caddis larva case found in a small, slow moving stream with a muddy bottom. There are many species of caddis fly in the UK and this one has made its case from grit, twigs and bark in order to construct a home and to act as camouflage from predators. In this picture the caddis larva can be seen emerging from the entrance to its case. White background. North Dorset England UK GB
