About Hadena confusa (Hufnagel, 1766)
Hadena confusa (Hufnagel, 1766) has a wingspan of 27–35 mm. Its forewings have a purplish fuscous ground colour tinged with olive grey. The forewing stigmata are fused into a single large white patch, with a small white apical blotch. The irregular wavy white subterminal line connects to the apical white stain. The basal forewing field shows more or less noticeable whitening, and the fringe is chequered. The hindwings are fuscous with a small discal lunule and white fringe, and are slightly darker along their outer edge. Melanistic individuals can occur in very humid areas, primarily in the Shetland and Orkney Islands, parts of the Hebrides, Wales, and Scotland.
