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 with a white spot edged by brown, and two orangey-brown markings, along the front edge of the forewing. The wings are quite angular in appearance. There are several other yellow moths with brown markings: if seen well, the Brimstone can be distinguished by its unique brown markings and white spot.
