Agrotis exclamationis L Heart dart moth

Although an often abundant moth, larvae of this pest are far less troublesome than those of the previous species. Larvae (up to 35 mm long) are similar to those of Agrotis segetum (p. 234), but the adfrontal plates are pointed apically (Fig. 318b), the body less shiny and the spiracles noticeably larger. They feed from July onwards, normally overwinter as fully fed individuals and pupate in the spring. Adults (38-40 mm wing-span) are mainly brown with blackish markings (including a distinctive black "dart') (Fig. 316b) and greyish (female) or whitish (male) hindwings; unlike the previous species, the antennae of male moths are not noticeable bipectinate (Fig. 317b). They fly in June and July.
