Eupithecia shirleyata Cassino & Swett, 1922
23 mm according to Wikipedia
"In spite of the differences noted in the original description as distinguishing the species from subapicata, the only superficial one that seems to hold is the smaller size. There are tendencies towards a duller wing coloration, especially in the males, and the pale apical areas may be somewhat reduced in size, but these features do not always hold. The genitalia in both sexes offer, however, good characters." (1)

Southern California (Pasadena, SanDiego, and adjacent areas). (1)
"end of November until late March or even early April" (1)
