Insects of Britain and Ireland: the genera of Lepidoptera-Geometridae
Adults. Crepuscular and nocturnal. Antennae of males bipectinate; apically simple. Face smooth.
The outer margin of the forewing convexly curved, or sigmoid-curved. Forewings whitish-ochreous; with a clear discal mark (this grey, linear); traversed by a conspicuous, oblique red stripe (this continued to near the middle of the inner margin of the hindwings). The outer margin of the hindwings angled. Hindwings conspicuously patterned; whitish-ochreous; without a clear discal mark; transversely lined (with spectacular red median and marginal lines).
Vein 10 of the forewings arising out of vein 9. Hindwings exhibiting a tubular vein 5. Vein 5 of the hindwings arising from about the middle of the transverse vein. Vein 8 of the hindwings shortly anastomosed basally with the upper margin of the cell, thence rapidly diverging. Hindwing veins 6 and 7 stalked.
Posterior tibiae of males 4-spurred (likewise the female).
Early stages. Larvae feeding on Polygonaceae and Chenopodiaceae.
British representation. 1 species; South-east England, Central-southern England, South-west England, English Midlands, Northern England, Southern Scotland, Northern Scotland, Wales, and Ireland. Living adults found June and July. T. comae (The Blood-vein).
General comments. Comparisons of Newman, Meyrick and Edelsten et al. with the Bradley et al. (1972) edition of Kloet and Hincks's check list reveal horrendous nomenclatural confusion over Timandra, Cyclophora, Colothysanis and Scopula; see especially the Blood-vein and the Maiden's Blush, for which identical nomenclatural combinations have been freely interchanged.
