Yorkshire Status: Fairly common and fairly widespread resident.

This is the last of the Thorns to appear and it appears in our traps in late Autumn. It is the only Thorn to hold its wings flat, making identification easy. Occasionally we see the paler and slightly larger females. It is commonest in broad-leaved woodland but is often seen in gardens. In good habitat, it can be found in good numbers for example 47 at Ellington Banks on 30/10/2007.

Sutton & Beaumont, 1989: Recorded from all five vice-counties but often seems less common than some of the previous species. Possibly less recorded at light due to its later flight-period, larvae are widely reported over the county.
