Puss Moth Cerura vinula
Wingspan 45-70 mm.
Named after the cat-like appearance of the adult moth, this species is fairly common throughout most of Britain.
The striking caterpillar feeds on aspen (Populus tremula) as well as poplar (Populus spp.) and willow (Salix spp.). When disturbed, it raises its head and waves the twin tails, which have pinkish extendable flagellae.
The adult flies from May to July, and frequently comes to light.
