Bent-winged Owlet, Variable Snout Moth
Bleptina caradrinalis is a small erebid commonly known as the bent-winged owlet or variable . It was described by Achille Guenée in 1854.

Identification
The bent or angled outer margin of the distinguishes this from many similar herminiine . The combination of moderate size (22–32 mm wingspan), dull -gray coloration, and forward-projecting labial ('snout') aids recognition. The specific epithet 'caradrinalis' references superficial resemblance to certain Caradrina species. examination may be required for definitive identification from closely related Bleptina species.
