Brush-footed butterflies

Issoria lathonia

Queen of Spain fritillary

Its hindwing undersides carry large silvery-pearl spots so bright they look metallic, unlike any other European fritillary.

WhereDry meadows, heaths, and arable edges
Size38 to 46 mm wingspan
WhenApril to October

The upperwings are orange with rows of small black spots, but the underside of the hindwing is the giveaway: it is patterned with big, mirror-bright pearly patches unlike the smaller, duller marks of other fritillaries.

It is a strong disperser and can produce up to three broods in a season, with numbers building through repeated waves of colonisation rather than staying settled in one place.
