Scotopteryx luridata, the July belle, is a species of moth in the family Geometridae.

It is found in most of Europe, except Finland and the Baltic region.

The ground colour of the forewing is grey, with a middle darker band between two cross lines.

Very similar to Scotopteryx mucronata but the discal spot on the forewings lies closer to the antemedian line (inner line) than in mucronata and the hindwings are slightly darker and without markings.. See Townsend et al.[2] The caterpillars are brightly coloured and have a brownish stripe pattern.
