Orthosia populeti, the lead-coloured drab, is a moth of the family Noctuidae. It is found in Europe.
The wingspan is 34–40 mm. The length of the forewings is 15–17 mm. Meyrick describes it -Antennae in male bipectinated. Forewings brown-grey, slightly purplish-tinged ; first, median, and second lines somewhat darker, especially on costa ; orbicular and reniform darker, outlined with pale ; subterminal line pale greyish-ochreous, edged anteriorly in middle with two small red-brown or black marks. Hindwings grey. Larva pale green or greenish-whitish ; dorsal, subdorsal, and spiracular lines whitish ; head pale greenish-ochreous, more or less blackmarked.[1] Orthosia populeti is difficult to certainly distinguish from its congener Orthosia incerta See Townsend et al.[2]
The moth flies in one generation from the beginning of March to May [1]. The egg is greyish white with dark grey girdled dots. When full grown the caterpillar is whitish or yellowish green, but always whitish on the back: three white lines on the back, the central one rather broad; head ochreous brown with a blackish spot on each side. The caterpillars mainly feed on aspen.
