Insects of Britain and Ireland: the genera of Lepidoptera-Noctuidae
Adults. Head loosely scaled. Head with a frontal tuft. Eyes glabrous; not ciliated. Antennae of males bipectinate (with very short pectinations ending in long bristles, and thickened below the middle). Labial palps very long; obliquely ascending (thickened with rough scales, the second segment very long and straight, the terminal shorter and pointed).
Wingspan 30–33 mm. Thorax and abdomen concolorous with the forewings. Forewings pale greyish-ochreous, irrorated dark brown; patterned transversely; the patterning well marked (with three narrow, darker transverse lines: the first and second cloudy dark yellowish-brown, somewhat sinuate and bent near the costa, the subterminal one cloudy dark brown and nearly straight); reniform undefined; orbicular undefined; claviform undefined. Hindwings whitish, or whitish-fuscous (paler towards apex and costa); fairly conspicuously patterned; without a clear discal mark; twice transversely lined (with fairly obscure, dusky second and subterminal lines, and sometimes a dark terminal one); exhibiting vein 5. Vein 5 of the hindwings strong; arising nearer to vein 4 than to vein 6; parallel with vein 4. Thorax not crested. The males conspicuously fan-footed, via a long, expansible hair-pencil on each anterior tibia. Posterior tibiae with spines; with appressed scales. Abdomen not crested.
Living adults found May to July.
Larvae, pupae. Larvae posteriorly rounded, or posteriorly tapered; feeding on foliage of Betula (including catkins in the Spring) and Quercus; pupating on vegetative parts of the foodplant, or on the surface of the ground.
British representation. 2 species; South-east England, Central-southern England, South-west England, English Midlands, Northern England, Wales, and Ireland; P. strigilata (Common Fan-foot), P. plumigeralis (Plumed Fan-foot).
