It is found commonly in many habitat types in the southern half of Britain, including Norfolk.
The female lays eggs singly on the underside of the host plant (mainly wild privet) leaves and stems. After 9-20 days, the pale yellow larva hatches. Even at this early stage it has a distinctive dark horn. Larvae rest beneath midrib of leaf, but when fully grown, hang upside down, most likely clinging to stripped shoots, within two metres of the ground.
