Papaipema cerussata
Grote, 1864
ironweed borer moth
Papaipema cerussata, commonly known as the ironweed borer , is a noctuid moth found in eastern North America. The species is a stem-borer , with larvae that feed internally on the stems of Vernonia noveboracensis. It has been documented across seventeen states from Maine to Georgia. The specific epithet 'cerussata' refers to the lead-white coloration characteristic of this species.

Identification
The specific epithet 'cerussata' (meaning lead-white) suggests distinctive pale coloration that may aid in identification. As a member of the Papaipema, it likely exhibits the slender body form and relatively plain forewings typical of stem-boring noctuids. Definitive identification may require examination of genitalia or larval association with Vernonia noveboracensis.

Taxonomic History
Originally described by Grote in 1864 as Gortyna cerussata, later transferred to Papaipema. The basionym reflects early uncertainty in noctuid classification.
