Cryptic diversity in a vagile Hawaiian moth group suggests complex factors drive diversification

The sphinx moth genus Hyles has unexpected diversity across the Hawaiian Islands. Molecular systematic analysis reveals four cryptic lineages in well-known group. Many Hyles are highly vagile, but the genus generates single island endemics. Some Hawaiian Hyles single islands endemics have multi-island sister species. Despite shared ecologies, some species are common, while sister species are rare.
