Oak eggar moth
The oak eggar moth ‘Lasiocampa quercus’ is apparently named ‘oak’ because the cocoon is similar in shape to an acorn.
Fairly common on Forest heathlands, the swift-flying males are occasionally seen by day, in sunny weather.
Females are nocturnal and attracted to light at night, but when newly hatched can attract many males by releasing pheromones.
The large brown mottled, hairy larva feeds on heather, bilberry and bramble and also leaves of various trees.
Look out for these moths from July to August, resting in grass or low vegetation.
