Papaipema maritima

Bird, 1909

maritime sunflower borer moth, giant sunflower borer moth

Papaipema maritima is a noctuid native to North America, first described by Henry Bird in 1909. The larvae are specialized stem borers that tunnel into the stems of giant sunflower (Helianthus giganteus), creating distinctive stem galls. The species has experienced significant decline and is classified as a species of special concern in Connecticut, where it is believed to be extirpated. Its specialized relationship and loss contribute to its vulnerable conservation status.
