Trichoptera, Caddisflies

General Description

Most adult caddisflies can be easily mistaken for moths. However, moths have scaly wings, while caddis have hairy wings. Some species have antennae longer than their body but for most the antennae are shorter. Generally dull coloured: black, brown or grey. Usually 1-2 cm in length but usually under 0.5 cm. Males often smaller than females.

Biology

Adult caddisflies live for a few weeks, possibly up to a month in some species. Males are often smaller than females. They are usually most active at night and can be readily attracted to lights set up beside a water body. In temperate regions they are only likely to be seen between late spring and autumn. They do not feed but may take some nectar.
