Most butterflies are small or medium sized. Below usually white or brown. Upper side is colourful mainly brilliant blue, green, orange or violet. Despite the name, many species have no blue. The hindwings have tails or tail like appendages [small tufts to long fluffy tails]. Few HW with lobes. Often have a dark spot at the base of tail making decoy perfect. Fore legs are perfect in both sexes and suitable to walk, but the tarsal segments of male fore legs are fused hence males use only four legs. Hindwing without precostal veins.  FW radial vein has only 3 or 4 of the 5 branches. Antennae are set close together on top of the head with bases touching the eye.

 The eyes are large and close together. Eggs tiny, turban shaped or dome like, with notches like a golf ball. The larvae are oval with segmented body and hidden head.
