Ectropis bistortata Goeze, 1781 The engrailed and small engrailed (Ectropis crepuscularia) are moths of the family Geometridae found from the British Isles through central and eastern Europe to the Russian Far East and Kazakhstan.

The western Mediterranean and Asia Minor and the Caucasus represent the southern limit of the distribution (with the Balkan countries).

In the north, the distribution area ends at the Arctic Circle.

[1][2] [3] The ground colour of the wings is buff or grey, variably marked with darker fascia and a pale postdiscal crossline.

The greyish caterpillar is truly polyphagous, feeding on a huge range of plants.
