Common quaker

It is often one of the first moths at light traps in late winter, feeding on willow catkins before most other moths have emerged.

The common quaker is a variable moth ranging from greyish brown to reddish brown, with large rounded stigmata outlined in a paler shade and a straight subterminal line near the wing edge. The hindwings are duller and greyish.

Caterpillars feed on oak, sallow, and other deciduous trees through spring, and the single yearly generation emerges from late winter into spring, when adults visit sallow blossom and blackthorn flowers at night.
