The Long-tailed Blue (Lampides boeticus) is named for the wispy ‘tails’ on the trailing edge of each of its hindwings. Also known as the pea blue, the male is a striking violet-blue colour, while the female is a mix of duller blue and brown. There are two black spots by the tail on both sides of the wing. It can be found in Europe, Africa, South and Southeast Asia, and Australia.
