Dotted Border Agriopis marginaria
Wingspan 27-32 mm.
A common species distributed widely over the British Isles, there are quite a number of variations, including a virtually all-dark form, ab. fuscata.
The females are flightless, and have only vestigial wings.
The moths are out from February to April, when the males can be attracted to light.
The species frequents woodland, gardens and bushy places, and the larvae feed on several different deciduous trees.
