Explanation of Names
Specific epithet pallidata is Latin meaning "pale."
Size
Wingspan about 21-22 mm. (1)
Identification
(Ann Hendrickson) At least in Edwards County, Texas, I have found them to be dimorphic. The males generally have darker PM areas with smudges:

and the females often have V mark at vein 3 along the PM line, like this example:

However, some females are completely plain. VERY hard to determine species visually.
Range
Southwestern United States.
Food
BugGuide records from Texas on Ashe's juniper (Juniperus ashei). (2)
Werner & Olsen (1973) reported the larval host as creosote (Larrae, Zygophyllaceae) but this is likely in error.
