Thorybes Bathyllus

The Southern Cloudywing (sometimes spelled Southern Cloudy Wing), Thorybes bathyllus, is a North American butterfly in the family Hesperiidae. There are two main reasons why Southern Cloudywings can be difficult to identify: one is individual variation and the other is confusing seasonal forms. In the south, where it has two broods per year, there are two seasonal forms. Spring forms are usually lightly marked and resemble Confused Cloudywings (Thorybes confusis). Summer forms tend to be more boldly marked by comparison, making identification easier. However, summer Confused Cloudywings are also strongly patterned which makes identifying them more difficult. There rapid flight is very erratic, though it is closer to the ground then in some of its close relatives.
