SilKarner BlueThere are about 4,000 species of small, delicate butterflies in this family. Most species are are brightly colored in blue, violet, or copper and have a metallic sheen. Some species have tiny tail-like extensions on their hindwings.

The males in this family have short forelegs and no claws. The females have normal forelegs. The caterpillars of the species in this family look more like slugs than caterpillars.
