Late May to July. Common in most of England and parts of Wales. The white edged ‘80’ on the forewings give this moth its common name.

A brown moth with fine dark cross-lines on the forewings curving around the 80 mark. The forewings are broader then the Figure of Eight moth. The adults fly at night and are attracted to light.

The caterpillars can be found from mid-July to September feeding at night and resting between two leaves spun flat together during the day. They overwinter as pupae in a delicate cocoon between leaves of the foodplant which fall to the ground with the leaves in autumn
