Pest status

Some members of the tipulid genus Tipula, such as the European crane fly, Tipula paludosa and the marsh crane fly T. oleracea are agricultural pests in Europe. The larvae of these species live in the top layers of soil where they feed on the roots, root hairs, crown, and sometimes the leaves of crops, stunting their growth or killing the plants. They are pests on a variety of commodities. Since the late 1900s, T. paludosa and T. oleracea have become invasive in the United States. The larvae have been observed on many crops, including vegetables, fruits, cereals, pasture, lawn grasses, and ornamental plants.

In 1935, Lord's Cricket Ground in London was among venues affected by leatherjackets. Several thousand were collected by ground staff and burned, because they caused bald patches on the pitch and the pitch took unaccustomed spin for much of the season.
