Taxonomy
Superfamily: Geometroidea Family: GeometridaeSubfamily: LarentiinaeTribe: EupitheciiniP3 Number: 910371.00 MONA Number: 7530.00
Identification
Field Guide Descriptions: Online Photographs: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLDTechnical Description, Adults: McDunnough (1949)                                                                                 
Adult Markings: The forewings are elongate, more than twice as long as wide, but triangular in shape with an oblique outer margin (Forbes, 1948); the are pointed apically and have a checkered fringe (McDunnough, 1949). The ground color is light fawn, tending to gray (McDunnough, 1949). The markings are often obscure (McDunnough) or or even, giving the appearance of striations (Forbes, 1948). The discal dot is slender. The second segment of the abdomen has a slight indication of a dark transverse band (McDunnough). Eupithecia matheri is similar in having narrow, elongated forewings and an early spring flight, but is grayer than swetti and has more obsolescent markings (Rindge, 1985). The hind wings are slightly paler than the forewings, and have a minute discal dot and may or may not have an extradiscal line or band (Rindge, 1985).
Wingspan: 22 mm (Forbes, 1948)
Adult Structural Features: The eighth sternite is not modified and is twice as wide as usual (Forbes, 1948); according to McDunnough (1949), it is broad and subtriangular with truncate apex. The palpi are of moderate length and tufted (McDunnough, 1949). In males, they extend beyond the front of the eyes by a distance about equal to the diameter of the eye and in the females are only slightly longer (Rindge, 1985); the palpi have some white scaling along the ventral edge.
Adult ID Requirements: Identifiable only by close inspection of structural features or by DNA analysis.
