The Buff-tip caterpillar is yellow with black chequered markings, light hairs and an upside-down yellow "V" on its black face.
It eats leaves of several types of common tree and shrub, generally in September before spending winter/spring as a pupa.
Many thanks to Darren Parsons for the above photos of the caterpillar.
