Material: VE, Larvik: Oddanesand, 58.96754°N 9.85292°E ± 50m, 18 August 2019, 8L, leg. AF, BOLD: NHMO-ENT-548140, coll. NHMO .

Biology: The white, later orange larvae develop singly in galled bracts of Achillea ptarmica ( Asteraceae). Infected capitula show no outward sign of damage. It is not stated whether the species has one or more generations per year. Pupation and hibernation presumably take place in the gall.

Distribution: Known from a few European countries including Norway and Denmark.
