The taxonomic position of this species has been confusing. It was synonymized with Eupithecia absinthiata but constant, though small, differences in the DNA of both species led to the decision to regard it as a separate species.
Length 14–16 mm, constantly smaller than the larva of Eupithecia absinthiata (18–20 mm); more rosy-reddish than the larva of E. absinthiata and with five more strongly contrasting dorsal spots.
One generation a year: from mid-July to mid-August.
Oligophagous, but preferably on Calluna vulgaris.
Heathland, moorland, peat-bogs, forest edges with abundant Calluna growth.
