the black margin of the hindwing is wider and more sinuate; the (6) spots of the forewing below are not confluent; Riviera. – italica Dziurz. [ synonym of ssp. collina Burgeff, 1926 ] the same, but has only 5 spots; Northern Italy. – Larva green, with black dorsal stripe, and yellow lateral line, above which there are triangular black spots. Pupa black, abdomen greenish white; in a light-yellow cocoon. This species is very similar to Zygaena filipendulae. They can be distinguished by the color of the apex of the antennae (whitish and sharper in Z. transalpina, black in Z. filipendulae). Moreover, in Z. transalpina, spot 6, when present, is clearly separated from stain 5, and even spots 3 and 4 are more distant than in Z. filipendulae. Biology Adults are on wing from the end of May to August in one generation per year. The imagines are lively and active insects, taking perhaps quickest to the wing of all the Burnets. They likewise simulate death when suddenly touched, but revive soon and whiz quickly away, the flight being fast. It is an aposematic species because its warning colors signal it as toxic to predators such as birds and lizards. In case of attack, it emits a liquid containing cyanide. The larvae feed on the leaves of Hippocrepis comosa and sometimes Coronilla varia and Lotus corniculatus. Larvae can be found from August, after overwintering, to June of the following year.
