([Denis & Schiffermüller], 1775)
Wingspan 23-27 mm.Superficially similar to P. pallidactyla, this species has the hindleg banded brown and white below the middle spurs, and is often more distinctly marked on the forewing.
It occurs, sometimes commonly, over much of England and Wales, and flies in July.
The larvae feed on tansy (Tanacetum vulgare), mining down a shoot, hibernating through the winter in the roots and burrowing up another shoot in the spring.
