Identification
The can be distinguished from related tachinid genera by features of the and , including the angular or elongated antennae suggested by epithets such as 'angulicornis' and 'rostrata'. The specific diagnostic characters require examination of and original descriptions. Identification to species level depends on subtle differences in wing venation, body proportions, and male terminalia.
Distribution
have been described from North America, with records from the United States and Canada. The type locality for C. rostrata (Coquillett, 1898) is Colorado. Specific range limits for most species remain undefined due to limited collecting and taxonomic study.
Ecological Role
As members of the Tachinidae, in this are presumed to function as of other insects, though no verified records were found in the consulted sources. The tribe Blondeliini is known to parasitize various Lepidoptera and other insects.

Taxonomic history
Townsend (1916) established this based on distinctive antennal and facial characters. The genus has received limited subsequent taxonomic attention, and no modern revisions are available. The six included have not been comprehensively reviewed since their original descriptions.
Etymology
The name derives from Greek 'chaeto-' (bristle, hair), 'stigma' (mark, spot), and 'ptera' (wings), likely referring to bristle-like markings or setae on the wings.
