Perizoma blandiata, the pretty pinion, is a moth of the family Geometridae.

It is related to P. minorata but with the band between the basal and median obsolete or very shadowy (extremely pale brown) the median band very dark anteriorly but pale in the middle, except on the veins, the hindwing rather more strongly marked.

has the median band dark throughout and appears to form a constant local race in the Hebrides.

[2] The larva is short and powerful with short bristles and pale green with a wide red longitudinal stripe on each side of the back.This colour combination represents an excellent camouflage and can be interpreted as an imitation of the reddish stem of the Euphrasia on which it feeds.

There is one generation per year with adults on wing from the end of July to August.
