The Common Blue Butterfly (Polyommatus icarus) is of the family Lycaenidae which is in the genus Polyommatus. This species has a widespread distribution across the Palaearctic region and in 2005 it was found as an invasive species in Mirabel, Quebec, Canada where it has continued to extend and colonise new areas. In southern Europe, the flight season is protracted, from early March into November, over a number of generations. In Britain and Ireland, it is on the wing from May to late September, over two generations 
The male has striking blue upper wings and lighter brown and blueish washed under wings compared to the female's brownish upper and under wings although her upper wings can be blueish brown in some populations. Males are very territorial and are constantly in search of receptive females. When the sexes meet, copulation occurs immediately, usually without any courtship ritual. Eggs are laid on the preferred larval food plant Birdsfoot Trefoil (Lotus corniculatus) or on plants from pea and bean family (Leguminosae). It overwinters as a larva (caterpillar) which emerges from hibernation the following season to continue feeding on its larval plant.

The Common Blue (Polyommatus icarus) is a small butterfly in the family Lycaenidae. It occurs throughout the temperate regions of Europe (including The Canary Islands) Asia and North Africa. In Europe, it is absent from Iceland, the Atlantic islands of Madeira and the Azores. As its name implies it is one of the most widespread and commonly encountered blue butterflies in the Palaerarctic  region. In 2005, it was discovered breeding in Mirabel, Quebec, Canada and it has since increased its distribution there. In southern Europe, it is on the wing from late March to early November but it has a shorter  flight (May to September) season in the northern parts of its range.
