Chalk Hill Blue, Itchen Navigation, Hampshire
Lysandra coridon has a wingspan of 30–36 millimetres (1.2–1.4 in).[4] These small butterflies present a sexual dimorphism. This species' physical appearance can be described as males having pale silvery-blue upperside of the wings with a submarginal line of grey spots on the hindwings and a thin brown and white chequered fringe. Females have dark brown upperside of wings, with marginal orange spots and also with chequered fringes.[5] The underside of the wings show a light ochre colouration, several dark spots surrounded by white, a submarginal line of black marks, a series of marginal orange spots on the hindwings and a blue dusting near the body.
As with many blue butterflies, separation from similar species in the field is on the underside markings. Aberrations are common.
