This is the species of blue which people are more likely to be familiar with. The male's upper wings are bright blue with a fine black border and white fringe. The female's upper wing colour is variable and can range from brown with the barest tinge of blue through to almost all blue and they have a row of orange lunules at the wing edges. The main habitat is short turfed grassland, often rabbit grazed. Commonly seen around the coastal areas but also fairly well, but thinly, distributed inland. The caterpillar foodplant is Common Bird's-foot Trefoil. Double brooded and therefore seen in May/June and August/September. Overwinters as a small caterpillar.
