Insects of Britain and Ireland: the genera of Lepidoptera-Geometridae
Adults. Antennae of males simple; simply-ciliate. Face rough (with a short cone of scales).
Wingspan 24–26 mm. The outer margin of the forewing convexly curved. Forewings rather dingy, light brownish grey; with a clear discal mark (this black, connected to the costa by a dark fuscous streak). The outer margin of the hindwings somewhat scalloped (or wavy). Hindwings conspicuously patterned (similarly to the forewings); brownish grey, like the forewings; with a clear discal mark to without a clear discal mark; conspicuously transversely lined (with dark, wavy basal, median and outer lines, and a zigzag marginal one).
Vein 10 of the forewings arising independently of 9; arising independently, anastomosing with 11 and 9 to form a double areole. Hindwings exhibiting a tubular vein 5. Vein 5 of the hindwings arising from about the middle of the transverse vein, or arising from below the middle of the transverse vein (?). Vein 8 of the hindwings approximated to or anastomosed with the upper margin of the cell to the middle or beyond. Hindwing veins 6 and 7 stalked.
Posterior tibiae of males 4-spurred.
Early stages. Larvae feeding on Lysimachia.
British representation. 1 species; South-east England, Central-southern England, South-west England, English Midlands, and Northern England (local). Living adults found in June. A. sparsata (Dentated Pug).
General comments. The hindwing margins distictly dentate.
