The green pug (Pasiphila rectangulata) is a moth of the family Geometridae. It is sometimes placed in the genus Chloroclystis or Rhinoprora. It is common throughout the Palearctic region (from Ireland to Japan) and the Near East, but also appears in North America.

Typically this species has green wings with distinct dark bars but it can be quite variable and is often mostly dark brown with little green. The green coloration also fades over time. "Green, more or less dulled with black, the lines black, the postmedian forming sharper angles than in the two following (C. debiliata, C. agitata). Underside very sharply marked. - In ab. subaerata Hbn. the black markings are reduced, only the antemedian and the postmedian line developed. -In ab. cydoniata Bkh. the black is increased, particularly in the median area. - ab. cydoniata is entirely or almost entirely black."Prout, L.B. 1912–16. Geometridae. In A. Seitz (ed.) The Macrolepidoptera of the World. The Palaearctic Geometridae, 4. 479 pp. Alfred Kernen, Stuttgart.

It flies at night in June and July and is attracted to light.
