The large size and striking wing patterns of this moth makes it difficult to confuse with any other species in the area. The coloration is quite variable, but there are three main forms. In the typical form, wings are light with extensive brown and black shading. In the "dendraria" form, much of the shading is absent, and the median and ST lines are much bolder than other lines. The "carbonaria" form is a melanic, and wings are mostly black with some white lines or patches.
Forbes (1951) provides the only key to this genus, which is summarized here.
Moths of the genus Lytrosis are similar in size, but have a much different wing color pattern.
Distribution pattern: Eastern.
With the possible exception of detexta, the other 4 moths in this genus are restricted to Florida and are very poorly known.
