The wingspan is 27–35 mm. There is a strong sexual dimorphism.

The males have normally developed wings. The forewings are dark golden yellow or orange yellow to light brown and dusted with many black scales. There are three brown-grey transverse bands the outermost broken. Sometimes there are large black patches in the postdiscal area. The hindwings have the same basic colour as the forewings, but are however always paler with two thin, dark lines. The antennae are double saw combed.

The flightless females have almost entirely vestigial wings, a clumsy body, tapering at the end of body shape and are grey brown. The stub wings have are grey with two black crosses. Adults are on wing from October to November.

The larvae feed on various deciduous trees, including Betula, Quercus robur, Sorbus aucuparia, Rosa and Prunus padus.

gollark: Google has these TPU things, which are hyperspecialized for particular big parallel operations™ and have tons of memory bandwidth.
gollark: CPUs do a few fairly sequential and varied tasks quite fast; GPUs do big parallel boring ones extremely fast.
gollark: No, the majority of a GPU is just big SIMD things nowadays.
