Thorybes is a of skippers in the Hesperiidae, commonly known as cloudywings. The genus contains approximately six distributed across North America, with reflecting their geographic ranges (northern, southern, western, confused) or specific epithets. Species within this genus are medium-sized butterflies with characteristic dark, cloudy wing patterns. Taxonomic placement has been debated, with some sources treating Thorybes as a subgenus within Cecropterus.

Identification
Cloudywings are recognized by dark brown to blackish wings with variable pale spots and bands that create a "cloudy" appearance. They possess the robust body and large typical of skippers, with relatively broad forewings. -level identification often requires examination of the number and arrangement of pale spots on the forewing, the presence or absence of a white spot at the forewing end, and subtle differences in wing shape and fringe color. Males have costal folds on the forewings containing specialized scent .

Distribution
North America, with ranging from southern Canada through the United States to Mexico. Individual species have distinct regional distributions: Thorybes pylades (northern cloudywing) occurs across northern and eastern North America; T. bathyllus (southern cloudywing) in the eastern and central United States; T. diversus (western cloudywing) in western North America; T. confusis (confused cloudywing) in the southeastern United States including Florida; T. drusius in the southwestern United States (Southeast Arizona, Southwest New Mexico, West Texas) and Mexico.
Similar Taxa
- AchalarusSimilar dark-winged skippers with cloudy patterns; Achalarus often have more contrasting pale markings and different wing proportions
- ErynnisDuskywings share dark coloration and can occur in similar ; Erynnis generally have more pointed forewings and lack the broad, diffuse pale bands characteristic of Thorybes
- CecropterusSome taxonomic treatments subsume Thorybes as a subgenus within Cecropterus; boundaries and relationships remain under study

Taxonomic Uncertainty
The rank of Thorybes has been disputed. While widely treated as a , NCBI and iNaturalist classify it as a subgenus within Cecropterus. The Catalogue of Life places it in Pyrginae rather than Eudaminae. These discrepancies reflect ongoing research in skipper .
Species Delimitation
Thorybes confusis and T. bathyllus are particularly difficult to distinguish and may hybridize where ranges overlap. Field identification often requires close examination of wing spot patterns and, in some cases, genitalic dissection.
