Scientific name: Polyploca ridens
Mid-April to mid-May. Found in the southern half of England and most of Wales. A rather distinctive greenish moth with raised tufts on the thorax.
The forewings are marbled with black and white markings. They fly at night and are attracted to light.
The caterpillars can be found from late May to mid-July feeding at night and resting on the underside of a leaf during the day. They overwinter as pupae under moss at the base of a tree in leaf litter or soil.
