General comments:
Widespread resident.

Unlike Blair's Shoulder-knot, this species hibernates in the adult stage and so there are two peaks of flight, though only a single generation. It is a widespread though somewhat local species and can be expected in places where oaks grow and where there are also suitable places to hibernate, such as tree hollows, a loose bark and synanthropic habitat, such as garden sheds. The supposed British subspecies lactipennis Dadd has recently been shown to be a synonym of the mainland European subspecies ornitopus Hufnagel (Ronkay et al, 2001).
