description Holly Blue Overview
The holly blue (Celastrina argiolus) is a small butterfly found across Europe and temperate Asia, easily recognized by the pale silvery-blue upperwings of the male. It is one of the most familiar blue butterflies in the Lycaenidae family and frequently appears in gardens and woodland edges. Females lay eggs on holly in spring and ivy in summer, allowing two broods per year to use different host plants. Caterpillars are attended by ants, a relationship common among lycaenids.
