Melitara is a of snout moths (Pyralidae: Phycitinae) established by Francis Walker in 1863. in this genus are herbivores of cacti, particularly Opuntia species, with larvae that bore into cactus pads and stems. The genus is taxonomically contentious, with some sources treating it as a synonym of Zophodia while others retain it as valid. Melitara species serve as for in the Braconidae, and have been studied in the context of of cacti and as potential competitors to the invasive South American cactus moth Cactoblastis cactorum.

Life Cycle

Complete with , larval, pupal, and stages. Larvae are cactus-borers that feed internally within plant tissue.

Behavior

Ecological Role

herbivore of native and cultivated cacti. Serves as for native . Potential agent for cacti; also part of the native cactus-feeding that may interact with the invasive Cactoblastis cactorum.
