Description: Franclemontia interrogans is a medium (36mm) species that is a combination of tan and brown. The front wings are colored light tan towards the basal half of the leading edge as well as the trailing half. A non-distinct black line orginates at the base of the wing and runs toward the outside edge, bissecting the wing. The anterior side of this line has light brown shading, especially toward the outside of the wing. There is a white stigma-shaped mark in the black/light brown area. The hind wing is either uniformly gray with light veins or tan with brownish shading on the outside half.
Similar species: Other Noctuids that have a similar overall coloration do not have the white stigma-like marking, and those that have a similar white marking do not have the same arrangement of coloration as Franclemontia interrogans.
North American Range: This species ranges on the outer coastal plain of Virginia, North Carolina, South Carolina, Florida panhandle and Alabama. In Virginia it has been documented in Virginia Beach City.
VA Observations by Locality: Virginia Beach, City of
Flight season and broods: Adults fly in April. This is a single brooded species.
Habitat and Food Plants: The habitat is not well known, but a good stand of cane is essential. The larvae food plant is cane.
Behavior and Ecology: Larvae are present most of the year, but it is uncertain whether larvae or pupae overwinter.
Population trend and potential threats: Population trends are unknown. A major threat to this species is conversion of habitats to pine plantations and developments. Fire at inappropriate seasons could also threaten this species.
Management practices: In managed areas using fire, adequate refugia must be present and excessively frequent burning should be avoided. Since little is known about this moth, management practice recommendations for Papaipema should be followed.
