June to early July. A nationally scarce moth restricted to counties in southern England.
The wings are a dull green colour with a gold leading forewing edge and two fairly straight, white cross-lines. Similar to Little Emerald but a stronger green in colour.
The adults fly at night from dusk and are attracted to light. The caterpillars can be found from July to August before overwintering as pupae suspended by threads from the foodplant or in leaf litter.
