Puss Moth Larva

The amazing 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.
This larva was bred by myself at home this year on potted Willow
