This family of butterflies gets its name from its front legs. They are shorter than the other four legs, and they don't use them to walk or stand. These front legs don't have feet, just little brushes of hairs that the butterflies can use to smell and taste with. Sometimes the front legs are so small you can't see them.
This is a very diverse group of species. Some are brightly colored, some well camouflaged. Most have brown camouflage patterns on the underside of the wings, and brighter colors (often orange) on top, but there are lots of exceptions. Some have rounded wings, some have irregular edges with notches and little curves. Several species in this group are mimics, they look like other species that are toxic, and so avoid predators.
Many of the caterpillars have horns or spines or bumps to discourage predators. Some are dark colored, some are green or yellow, many have stripes or spots.
