Cerapteryx graminis L Antler moth

The antler moth is a sporadic pest of grasses, especially hard-textured species. Although present in various lowland sites, most damage is caused in upland areas. The larvae, sometimes known as 'armyworms', damage the roots and shoots; they occasionally migrate in large numbers, devouring grasses as they advance, and can then cause death of plants over a wide area.

BIOLOGY

The moths are usually most abundant in August and early September. They fly both at night and during the daytime, often in considerable numbers. Eggs, usually about 200 per female, are dropped at random as the moths fly over grass-
