Introduction: Brown with two grey spots on the forewing, with the larger spot kidney-shaped.
Identification: Adults are brown moths with two grey spots on the forewing, with the larger spot kidney-shaped. Males have antennae with obvious comb-like pectination, unlike most other similar looking moths. Wings are held flat over the body rather than roof-like. Caterpillars are plump, smooth, and greasy looking.  Single wing span. Body size up to 2.5 cm.
Max. Size: 2.5 cm.
Distribution: eastern and southen australia
Habitat: Open woodland, grasslands and cropping areas west of the Dividing Range and alpine boulder fields
Biology: Adult female moths lay eggs in open pasture and cropping areas, the caterpillars live in the soil by day, emerging at night to feed on herbs. They often sever the food plant at the base and drag the leaves back to shelter in the soil, hence the common name “cutworms”. Adults emerge in late spring, and form massed migratory flights which travel along the Dividing Range in eastern Australia until they reach high altitude areas where they spend the summer. They then return to the plains area in late summer to mate and lay eggs. This behaviour allows them to escape the heat of summer in the open plains. The adults are important food items for alpine predators, such as the Mountain Pygmy Possum, caterpillars are occasionally pests of field crops.
Other Common Names: Cutworm
Family: Noctuoidea
Genus: Agrotis
Species: infusa
When seen: Oct to Apr, adults fly at night, but are often conspicuous when aggregating during the day. Caterpillars feed at night. Caterpillars in pasture and cropping areas, adults throughout temperate Australia, but especially in alpine boulder fields in summer.
