European Crane Fly

Tipula paludosa

Tipula paludosa, known as the European crane fly or the leatherjacket, is a part of the Tipula genus that is made up of over 2,000 species throughout the world. T. paludosa is native to northwestern Europe, however it has been introduced to the northern aspects of North America, including Canada likely due to soil dispersion and other human-mediated activities. T. paludosa has become a major pest of lawns, pastures, and hayfields, as its larvae cause significant damage to the roots, stems, and leaves of various plants, contributing to its invasiveness.
