1637 Lasiocampa quercus (Oak Eggar) Male

Lasiocampidae Wingspan: 60mm.

The day flying male dashes about over moorland looking for the newly emerged females, homing in on their pheromones. One morning, I was working though the catch from our garden moth trap, and got a surprise when a large brown moth flew over my shoulder. It had come inside the workshop through an open window, through an open door between rooms and up to the trap. Looking inside there was a female which had come in to light, so I put them both into a mating net where they coupled immediately. within a few minutes 4 more arrived through the same route, and between them there was much jostling to get to the female.
