Small Blue - Cupido minimus - male (top row) - female (bottom row). Wingspan 25mm. Britain’s smallest butterfly; extremely active in sunshine, lethargic on overcast days. Adults have smoky-brown upperwings, those of males having a purplish iridescence; underwings of both sexes are grey with small black dots. Flies June–July. Larva is grub-like and feeds on Kidney Vetch. Very locally common in England, Wales and southern Ireland; usually associated with chalk grassland because of larval foodplant’s requirements.
