collectively, these three groups of butterflies share many characteristics, especially in the egg, larval, and pupal stages. however, skippers have the antennae clubs hooked backward like a crochet hook, while the typical butterflies have club-like tips to their antennae, and moth-butterflies have feathered or pectinate (comb-shaped) antennae similar to moths. skippers also have generally stockier bodies and larger compound eyes than the other two groups, with stronger wing muscles in the plump thorax, in this resembling many moths more than the other two butterfly lineages do. unlike, for example, the arctiinae, though, their wings are usually small in proportion to their bodies. some have larger wings, but only rarely as large in proportion to the body as in other butterflies. when at rest, skippers keep their wings usually angled upwards or spread out, and only rarely fold them up completely.
