Scientific name: Scotopteryx luridata
June to August. Britain and Ireland. A pale grey moth with three darker cross-lines on the forewing and a central wing spot.
So similar to Lead Belle they are easily confused. In the July Belle the central forewing spot is usually smaller, rounder and usually closer to the second cross-line.
The caterpillars can be found from September to the following May overwintering as larvae before they pupate in a cocoon among plant debris.
