Abraxas grossulariata is a moth of the family Geometridae, native to the Palearctic realm and North America.

Its distinctive speckled coloration 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 strikingly patterned forewings have a white ground colour, with six transverse series of black stains, partly associated with a pale yellow basal cross band and another through the central area of the forewing.

Research using Abraxas grossulariata led to the discovery of sex-linked characteristics.
