Explanation of Names
Specific epithet is part of a series of Kearfott names originating from various alphabetical rhyming schemes with no meaning, often derided by subsequent authors as "nonsense names." See Brown (2001) for a humorous take on this "barbarous" practice. (5), (3)
Heinrich (1923) listed the wingspan 12-15 mm. (4)
"forewings of pale gray, somewhat brownish in tone, with fine striations of slightly darker gray, most evident towards the costa. The most eye-catching features are the two large blackish spots at the inner margin. The innermost spot forms half a crescent shape; the outer spot forms an approximate half-circle. When the moths is at rest, with wings closed, it appears to have a dark crescent followed by a dark circle in the middle of its back. In some specimens, these dark spots appear to be partially bordered by a narrow pale beige to whitish line. There are a few small blackish dots or spots near the anal angle" [description by Lynn Scott]

Forbes (1923) reported the flight period as August to September. (7)
