Similar species: Wormwood Pug Eupithecia absinthiata has stronger markings on the leading edge of the forewing and there is a dark band across the abdomen. The plain warm brown form of Common Pug Eupithecia vulgata is on average smaller (9 to 12mm), has stronger markings on the leading edge and has a darker base to the abdomen. The Jasione Pug is greyer with stronger markings and could be mistaken for Larch Pug Eupithecia lariciata or Golden-rod Pug Eupithecia virgaureata except both have a white or pale crest or spot on the thorax.
Forewing: 11 to 13mm
Habitats: Woodland rides, woodland margins, hedgerows, damp calcareous scrubby grassland and gardens.
Jasione Pug is found on dry acid grassland on coastal heaths and cliffs, vegetated walls and hedge banks.
Habits: The moth is seldom seen, although it occasionally comes to light.
Foodplant: The larva feeds in the ripening seed-capsules of Nettle-leaved Bellflower, Giant Bellflower and garden bellflowers.
The larva of Jasione Pug feeds on the mature heads of Sheep's-bit. Both forms pupate in loose soil.
