Wing span: 3.5-4.0 cm
Flight time: Most likely three broods, with adults flying from early May to mid August. It appears to be most often encountered in early May, from mid June to early July, and in mid August.
Status: Infrequent breeding resident.
Distinguishing features: This species and Thorybes pylades are quite similar. Both are brown in color with white spots on the upper forewing and have a series of dark brown markings on the lower hindwing. In T. bathyllus, the dorsal white spots are larger and hourglass shaped, the wing fringes tend to be paler, and the dark-brown hindwing bands appear solid rather than hollow. Additionally, males lack the costal fold.
Distribution and habitat: The Southern Cloudy Wing has been observed sporadically across the southeastern half Iowa, with outlying populations also occurring in the Paleozoic Plateau. It is most frequently encountered in xeric grasslands, including Loess Hill prairie, sand prairies, limestone and sandstone glades, and occasionally in old fields.
Natural History: The larvae of this species favor wild bean (Strophostyles helvola and S. leiosperma) and Goat's Rue (Tephrosia virginiana), which are most often found in dry, open, and often sandy places. One of the most impressive Southern Cloudy Wing populations occurs on the state's largest Goat's Rue population at the Big Sand Mound in Louisa County. As Goat's Rue is quite uncommon in the state, and essentially limited to the southeast, it is likely that Wild Bean constitutes the more frequent larval host.
