Leatherjackets eat the roots of your lawn, resulting in brown tufty patches, resembling Chafer damage, but looking its worst in March/April.
Most people are familiar with Crane flies or "Daddy Long Legs" - an insect that flies around on warm Autumn nights. It is often attracted into houses by the warmth and light, and can be seen dancing around lampshades or making shadows on walls.
The larvae of the crane fly is a grey-brown cigar-shaped grub called a "leatherjacket". These grubs hatch out under the grass in late August/September. They overwinter there until they stop feeding in mid-May to pupate, emerging as the leggy adults we know in August.
Often lawn damage is made worse by the badgers, foxes, magpies, and other birds which dig up the turf looking for a tasty meal.
