The buff arches (Habrosyne pyritoides) is a moth of the family Drepanidae. It is found throughout Europe and is well distributed in the British Isles except the far north of England and all of Scotland.

This is a distinctive and attractive species, its grey-brown forewings marked with bold buff-orange “arches." The hindwings are grey with white margins. The wingspan is 40–45 mm. It flies from June to August and is attracted to light and sugar.

The larva is orange-brown with a prominent white spot on each side of the head and feeds on bramble, hawthorn and hazel. The species overwinters as a pupa.
