Brenthia
Peacock Moths
Brenthia is a genus of small moths in the family Choreutidae, commonly known as peacock moths. The genus is notable for its caterpillars' remarkable defense strategy: they construct escape holes in leaves and use silken pillars to drop to safety when threatened. Some species exhibit striking wing patterns that mimic jumping spiders, a form of predator mimicry. Brenthia species are associated with specific host plants, with larvae feeding on various plant families including Boraginaceae and Malvaceae.
