British Insects: the Plume moths
Adults. Face tufted. Labial palps sub-ascending (second segment loosely scaled, the terminal one filiform). Wing-span 18–25 mm. Forewings conspicously cleft; 2-segmented; cleft from beyond the middle (from 2/3 to 3/4). The lower lobe expanded towards the apex. Forewings conspicuously patterned; red-brown, costa sprinkled whitish; with two oblique white fasciae, the first before the middle and sometimes interrupted, the second before the fissure; the cilia white towards the middle of the termen of each segment. The cilia towards the middle of the termen of each segment white. The base of the fissure preceded by a white fascia (this oblique, preceded by another before the middle of the disc). Forewing venation exhibiting the cell apically truncated. Forewing vein 8 present; 9 present (stalked with 8). Forewing vein 10 present. Forewing vein 10 separate. Forewing venation summary: 11 remote. Hindwings conspicuously cleft; 3-segmented (the posterior lobe narrower than the other two); reddish fuscous. Hindwings differently coloured from the forewings (darker). Hindwings reddish fuscous. Hindwings with a large black scale-tooth in the dorsal cilia of the posterior segment. The large scale-tooth in the posterior hindwing segment located much beyond the middle of the dorsum (almost apical, the middle third of the lobe whitish, the apical part dark reddish fuscous). The second lobe 3-veined. Hindwing vein 3 present (in the middle lobe).
Life history and botanical associations. Adults abroad July and August; not hibernating. Associated with shrubs; Crassinucelli; Rosales.
