Diaphania nitidalis
pickleworm, pickleworm moth
Diaphania nitidalis is a significant agricultural pest of cucurbit crops, particularly damaging to squash, cucumbers, and melons. Adults are nocturnal moths with iridescent brown wings marked by yellow bands and white borders. Larvae feed voraciously on reproductive tissues, flowers, and fruits, often burrowing into fruit flesh. The species is tropical in origin and intolerant of cold temperatures, limiting its permanent range to southern North America and tropical regions, though it migrates northward seasonally.
