Wingspan 40 to 50 mm. A spectacular species and one of our largest Geometrids. The wings are pale yellow marked with darker lines.

Woodland, scrub, hedgerows, parks and gardens.

Being strictly nocturnal and having quite a short emergence period from late june and throughout July, it is not often encountered by the non-enthusiast. There is occasionally a second brood when conditions are favourable.

The larvae feed on a number of trees and shrubs, but prefer Ivy.

Reasonably common in Britain, except for northern Scotland where it is local or absent. In a recent survey to determine the status of all macro moths in Britain this species was classified as common.

Fairly common in Leicestershire and Rutland. L&R Moth Group status = A (common and resident)
