Leatherjackets, the larvae of the crane fly (daddy-long-legs) attack the roots of a number of plants and damage lawns. Outdoors, eggs are laid in late summer to early autumn. Larvae then feed on plant roots and may damage the plant stem bases pupating early the following summer. On turf, birds looking for prey will cause further damage.
