Abstract
This study reviews the distribution, habitat, behavior, life history, larval host plant, dispersal ability, adult diet, mimicry, camouflage, predators, parasitoids, and microbiological data (chromosome number, pterin pigment, and genetic information) for all species in the Old-World snout butterfly genus Libythea. The adult of each species typically lands at damp spots on the ground, and visits flowers in low elevation mountains. Novel data from my field observations are also included. The male typically is territorial, and both sexes cryptically rest on branches. Most species are found in forests and disturbed habitats, and usually have one or two annual generations. The egg is generally laid on buds of Celtis (Celtidaceae), and in nearly all cases, the larva feeds on leaves of this plant genus. Little is known about the developmental stages of Libythea cinyras Trimen, L. collenettei Poulton & Riley, and L. narina Godart.
