European Crane Flies

The adult European Crane Fly looks like a large mosquito with longer legs. Crane fly larvae are sometimes called "leatherjackets" because of their tough exterior. The adults are often called "Mosquito eaters”, but do not actually eat mosquitos.

Damage

Crane fly adults do not cause harm to lawns or sting, but it is the larvae that damages lawns. European Crane Fly larvae are 1-inch long worm-like brownish maggots that eat grass roots, creating brown-yellow patches in lawns during the dry, summer season.

Location

European Crane Flies are predominantly found in the Pacific Northwest and New England.
