Common Blue

Common Blue

The Common Blue ,Polyommatus icarus, is a small butterfly in the family Lycaenidae, widespread over much of the Palaearctic and recently introduced in eastern Canada.



Male uppersides are an iridescent lilac blue with a thin black border. Females are brown above with a row of red spots along the edges and usually some blue at the base of the wings; the upperside may be mostly blue but it always has red spots. Undersides have a greyish ground colour in the males and a more brownish in the females. Both sexes have a row of red spots along the edge of the hindwings and extending onto the forewings, though they are generally fainter there, particularly in the males, where they are sometimes missing altogether. There are about a dozen black-centered white spots on the hindwings, nine on the forewings. These usually include one in the middle of the forewing cell, absent in Chapman's and Escher's Blues. The white fringe on the outer edge of the wings is not crossed with black lines, as it is in the Chalkhill and Adonis Blues.



The main food plant on most sites is Birds foot trefoil, Lotus corniculatus. Others used include Black Medick Medicago lupulina, Common Restharrow , Ononis repens, White Clover ,Trifolium repens, and Lesser Trefoil , Trifolium dubium. Eggs are laid singly on young shoots of the food plant.


The caterpillar is small, pale green with yellow stripes and, as usual with lycid larvae, rather slug-like. Hibernation occurs as a half grown larvae. They are attractive to ants, but not as much as some other species of blues. The chrysalis is olive green/brown and formed on the ground, where it is attended by ants, which will often take it into their nests. The larva creates a substance called honeydew, which the ants eat while the butterfly lives in the ant hill.
