Macrothylacia rubi, the fox moth, is a lepidopteran belonging to the family Lasiocampidae.
This species can be found from Western Europe to Central Asia and Siberia. These moths live in open woodlands, moors and prairies.
The wingspan of the male is 40–65 mm. The wings are reddish-brown in males, while females are usually paler, more greyish in colour and slightly larger than males. Both sexes show two narrow, straight, light-yellow, transverse bands, running across the forewings. The abdomen is thick, gray-brown and hairy. The caterpillars can reach a length of about 80 millimetres (3.1 in). They are initially black, with bright yellow or orange segments, later they become darker, always covered with blackish and tawny-coloured hairs and with light gray hair on the sides.
