Yorkshire Status: Local resident.
This is a moth of alder woodland and tends not to wander far from suitable habitat though it does occasionally turn up in gardens. It has a very distinctive resting posture with its wings held tightly shut. It is rarely seen in large numbers though in suitable alder woodland it can be moderately common, for example 19 trapped at the YNU meet at Askham Bog on 6/7/2022. It appears to have been common in Porritt's time as in 1907 he commented "occurs amongst alder, and often in abundance, almost everywhere". It then went into a bit of a slump but in recent years is has been doing quite well both in Yorkshire and nationally.
