Wing patterns are subject to variation, the most common form of aberration being a series of blue spots on the hindwing, known as ab. caeruleopunctata. These markings are visible on the specimen opposite.
Wingspan 26 - 36mm.
There are usually two broods each year. Larvae from Summer or Autumn broods overwinter. They resume feeding in March and pupate towards the end of that month. The pupal stage lasts from 25 - 30 days.
Generally May to August, but in some years may be found as late as October.
Widespread and sometimes common in Moray and in the south and east of Highland region.
