Abraxas grossulariata is a moth of the family Geometridae, native to the Palearctic realm and North America. Its distinctive speckled colouration has given it a common name of magpie moth. The caterpillar is similarly coloured to the adult, and may be found feeding on the leaves of shrubs such as gooseberry and blackcurrant. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
