Silphium Borer Moth, silphius borer moth
Papaipema silphii, commonly known as the Silphium Borer , is a described by Bird in 1915. It belongs to the Papaipema, a group of moths whose are specialized borers in the stems and roots of herbaceous plants. The species is found in North America and is associated with plants in the genus Silphium. The species has been assigned Hodges number 9498 in the North moth numbering system.

Identification
in the Papaipema are distinguished from other by their specialized larval biology as stem and root borers in herbaceous plants, though identification to species level requires examination of or association with plants. Papaipema silphii specifically is associated with Silphium host plants. Adults are -sized with typical dull coloration; precise diagnostic features separating P. silphii from are not documented in available sources.

Habitat
Associated with prairie and grassland where plants of the Silphium occur. The has been documented in northwestern Missouri, suggesting occurrence in tallgrass prairie regions of the central United States.
Distribution
North America. Documented occurrences include the central United States, specifically northwestern Missouri. The full extent of its range within North America is not precisely documented in available sources.
Seasonality
activity period is not precisely documented. A of a related (Antistrophus lygodesmiaepisum) associated with Silphium was photographed in late June in northwestern Missouri, suggesting potential seasonal overlap, though this refers to a different .
Diet
