Chalk Burnet

Zygaena fausta is a member of the family Zygaenidae, the day-flying burnet moths. Its bright aposematic colours of red, white and black on the wings indicate to possible predators such as birds that it is foul tasting or poisonous. In flight, the bright red abdomen is revealed, contrasting with the white legs and black head and antennae; the thorax is black and white with an eye spot on each side (see image). There appears to be a considerable variation in pattern among specimens from different parts of Europe.

The southwest of Europe is home to Zygaena fausta. The moth can be found from Spain and Southern Portugal to Western Austria and Southern Germany, northeast to Thuringia, and southeast to North-western Italy.
