Identification
Adult - forewing is light gray with three brownish transverse lines crossing the wing. The medial (M) and postmedial (PM) line are fairly straight and have a dark spot where they meet the costa. The antemedial (AM) line is slightly convex. The area beyond the PM line in both FW and HW is markedly darker gray, noticeably contrasting the paler median and AM areas of the wings. The PM line has a well-defined black blotch, or group of black spots, where it crosses the 2nd and 3rd medial veins, as opposed to some related species having a diffuse black blotch instead.
Range
Known from Arizona east to Louisiana, common in south Texas.(2)
Season
Adults can be found all months except January and July.(2)
Food
Larval host is Acacia smallii (Texas Huisache), now a junior synonym of Vachellia farnesiana (L.) Willd. (sweet acacia).
