About

The brimstone moth is a medium-sized, mainly night-flying moth that is on the wing between April and October when it frequently comes to lights in the garden. It can also be found in woodland, scrub and grassland habitats. The twig-like caterpillars feed on a variety of shrubs in the rose family, including hawthorn, blackthorn and rowan. The brimstone moth hibernates as a dense cocoon, usually on the ground.

How to identify

The brimstone moth is bright yellow; it has white spots edged with brown and two orangey-brown markings along the front edges of its forewings. The wings are quite angular in appearance. There are several other yellow moths with brown markings: if seen well, the brimstone moth can be distinguished by its white spot.
