Yellow-line Quaker Agrochola macilenta
Wingspan 32-36 mm.
Distributed throughout Britain, and commonest in the south, frequenting woodland, bushy localities, and moorland in the far north.
It flies from September to November, and feeds at various flowers and at sugar. It also comes to light.
In the north of its range, the caterpillars feed on heather (Calluna), but further south it generally lives on deciduous trees such as oak (Quercus) and beech (Fagus).
