It can be found in woodland, parks and gardens

May to July.

Found fairly frequently in England from Yorkshire southwards. In a recent survey to determine the status of all macro moths in Britain this species was classified as common.

Still fairly common in Leicestershire and Rutland, although this species may be declining. L&R Moth Group status = A (common and resident)
