Brenthia coronigera

Brenthia coronigera, commonly known as the metalmark moth,[1] is a species of moth of the family Choreutidae. It was described by Edward Meyrick in 1918. It is found in the Bengal region of what was British India.[2]

The adult moth is a mimic of predatory jumping spiders; the moth's forewings are held aloft and have bold black spots, which resemble spider eyes, while its hindwings, which are held in a twisted position and are marked with stripes, resemble spider legs. The moth also moves in a jumpy, jerky fashion, like a jumping spider, rather than fluttering like other moths. Its mimicry is so convincing that spiders respond by trying to court the moth, rather than attacking it.[1]

The larvae feed on Cordia obliqua and Cordia myxa.[3]
