Lasiocampidae Wingspan: 50-60mm.

A newly-emerged Female resting. THese fly at night, and when coming in to moth trap lights can seem enormous, but after they have settled, they seem to revert to a smaller size. This species readily lays eggs when put into a Keep Net during moth recording, so there are loads of eggs available on a night when they are flying. The males, like others in this group, dash over the Moors through the day searching for the newly emerged females.
