Comments: Currently this genus of 5 species is wholly North American and three of the species are found in North Carolina. The genus is quite similar to other “glaeas” and distinguished largely by features of the male valve and aedeagus.
Species Status: Recently described by Brou (1997). No specimens have been barcoded from North Carolina but those from Florida are distinct from any other Chaetaglaea species.
Identification
Field Guide Descriptions: Not in either field guideOnline Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: Brou (1997)Technical Description, Immature Stages: Apparently none                                                                                 
Adult Markings: This species resembles a C. rhonda but is darker and has a reddish sheen to the outer third of the forewing; the markings also tend to be less accentuated in fergusoni and there also usually a dusting of pale gray on the basal side of the postmedian (Brou, 1997). This species is also likely to be confused with somewhat worn specimens of Xestia dilucida complex but the reniform in that species is usually more strongly marked. Sexes are similar.
Adult Structural Features: The male valve is unique: deeply divided with just a thin anal member. The female genitalia are more robust than those of C. sericaglaea and lack the membranous section of the corpus ductus seen in C. rhonda.
Structural photos
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Immatures and Development: Apparently not yet described
Larvae ID Requirements: Identifiable only through rearing to adulthood.
Distribution in North Carolina
Distribution: Our records all come from the southern part of the Coastal Plain, including the Fall-line Sandhills.
