Their long and powerful legs are characteristic (thus: long-legged flies), and appear modified in some species. The legs are stretched out in resting position. These long, powerful legs enable them to run for long periods? and to jump long distances. Some species, walk sideways like beach crabs. The males have a distinctive, hairy brace apparatus on their abdomens.

Long-legged flies prefer to be in proximity to water. While some species prey on insects and worms, others feed on nectar and honeydew.

The females lay their eggs on rotting plants, under bark or in reeds. Some species lay their eggs in water. The larvae feed on plant substrates first, and later on small insects, often unselectively. The pupae have breathing tubes and are hidden in cocoons.
