Synonyms and other taxonomic changes
Eupithecia pusillata "of authors" (not Denis & Schiffermuller, 1775)
All-Leps treats the North American interruptofasciata as a distinct species, not a true synonym nor subspecies of the Eurasian E. pusillata
described by Packard in 1873
uncommon to rare in most of range
wingspan 15-20 mm, based on Internet photos
larva length to 16 mm
Adult: forewing grayish-brown with numerous dark transverse lines: single basal and median lines, and triple AM and PM lines; AM line sharply angled in middle; PM line jogs outward from costa; black oval discal spot interrupts median line; subterminal line pale, indistinct; terminal line checkered with dark and pale scales which continue into fringe; hindwing similarly colored but noticeably smaller than forewing

Larva: two distinct color morphs. The more common green morph has a green head and body, black middorsal stripe, and cream-colored lateral flange. The brown morph has a light tan head with dark markings; the body is rusty brown with a black middorsal stripe above the cream-colored lateral flange, and purplish brown below.
