Eupithecia bolterii (Hulst, 1900)

Tephroclystia bolterii Hulst, 1900

See this marked-up gray example for details: , and Ann Hendrickson's characteristic buff-colored example from Edwards County: .

[Adapted from McDunnough (1949), p. 589(1)] Forewings pointed apically (narrower than most other Eupithecia’s in region); ground color of forewings pale gray or buff; two dark brown oblique lines from the costa form a more or less evident triangular patch above the discal spot; the discal spot is elongate, black, upright; a dark streak runs from base of discal spot at least 1/3 towards FW base. There are often unmarked pale patches on the forewings on either side of the discal spot, and the upper (usually hidden) portion of the hindwings is typically unmarked, more so than on other species.

On unworn specimens, a black inverted "Y" or 3-bladed "propeller" on the buff thorax is usually conspicuous and seems to be diagnostic for bolterii, at least among Texas species.
