The v-pug (Chloroclystis v-ata) is a moth of the family Geometridae.

It is found throughout the Palearctic region, the Near East and North Africa.

The forewings of newly emerged adults are green with a characteristic V-shaped black mark which is part of a crossline.

The green colouring fades over time but the markings, small size (14–19 mm (0.55–0.75 in)) and triangular resting posture make this an easy species to identify.

The green larva, usually with three reddish stripes, feeds on the flowers of a wide range of plants (see list below).
