Occurrence
One finds this type of hot spots in the Alps to over 2,000 meters above sea level in southern highlands and generally in and generously to the Alps, in the Italian Alps, in Italy, with the exception of Sicily and on the Adriatic coast. They live in dry warm climates, especially on dry grass but also on flower-rich, higher-lying meadows. You are not frequent.
Way of life
The horseshoe vetch burnet sit in contrast to the six -spot burnet nectar eyes with spread wings on the flowers. The females lay their eggs in mirrors mostly from the lower leaf surface of forage crops. The caterpillars sometimes live in community. They overwinter and pupate in June of next year in an elongated, yellowish cocoon to stems and stalks.
The caterpillars feed on the leaves of the ordinary horseshoe vetch ( Hippocrepis comosa ), but rarely also of Colorful Kronwicke ( Coronilla varia) or Exceptional birdsfoot trefoil ( Lotus corniculatus ).
Flight times and caterpillars
The moths fly in one generation from late June to August. The caterpillars can be found in August and after hibernation until June of the following year.
