The forewing has a curved, blackish PM line, a prominent yellow subterminal line, a blackish discal spot, and yellowish scales along the veins. The fringe is black and the hindwing dark gray. Microtheoris ophionalis is a wide-ranging species that shows substantial geographic variation in coloration. Five subspecies are currently recognized, with populations in North Carolina conforming to the description above.
Forewing Length: 5.5-7 mm (Powell and Opler, 2009).
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: The larval ecology and life history are undocumented.
Distribution in North Carolina
Distribution: Microtheoris ophionalis has a very large range that includes southern Canada, much of the US, Cuba, Puerto Rico, Mexico, Guatemala, and northern South America. It is most commonly found in North America in a broad swath that extends from British Columbia southward to southern California and eastward through the Rockies and Great Plains to the Gulf Coast states and Florida. More scattered populations occur northward to North Carolina and the midwestern states. As of 2023, all of our records are from the southern Coastal Plain, including the Sandhills and maritime communities.
