Queen of Spain Fritillary; Sofia

Issoria lathonia

Description:

Female. The Queen of Spain Fritillary has very distinctive large silver spots on the underside hindwings so this butterfly is unlikely to be confused with any other species. Both sexes are very similar in appearance, although the female is slightly larger, with a shorter abdomen and a more greenish hue around the base of the upperside wings. The caterpillars are velvety black, heavily sprinkled with tiny white dots, and adorned with rows of dull orange spikes along the back and sides. They feed on field pansy Viola sp. Prior to pupation the larvae wander aimlessly for 2 or 3 days without feeding, and eventually attach themselves by the tail to a button of silk spun on the underside of a leaf, or a low stem. The pupa, which wriggles frantically if disturbed, is blackish-olive colour, marked with small white patches on the abdomen, which is adorned with a series of stubby white spikes. It bears a strong resemblance to a bird dropping. When feeding the wings are normally held almost fully outspread.
