Holly Blue Celastrina argiolus Wingspan 30mm. A familiar sight in mature gardens, especially if the larval foodplants (Holly and Ivy) grow nearby. In flight, looks rather silvery and can be hard to follow. Adult has violet-blue upperwings (seldom revealed at rest) and black-dotted white underwings. Double brooded: flies April-May and August-September. Eggs from spring brood are laid on Holly; in autumn they are laid on Ivy. Larva is green and grub-like. Fairly common in southern England, south Wales and southern Ireland.
