The Aganainae are a small subfamily of moths in the family Erebidae. The adults and caterpillars of this subfamily are typically large and brightly colored, like the related tiger moths. Many of the caterpillars feed on poisonous host plants and acquire toxic cardenolides that make them unpleasant to predators. Like the closely related litter moths, the adults have long, upturned labial palps, and the caterpillars have fully or mostly developed prolegs on the abdomen. The Aganainae are distributed across the tropics and subtropics of the Old World.
