* Macrolabis cirsii (Rübsaamen, 1890)

Material: NSI, Vefsn: Fustvatnet, Aspnes, 65.907643°N 13.361411°E ± 100m, 18 July 2019, on Cirsium heterophyllum, 2L, leg. HE, BOLD: NHMO-ENT-547974, coll. NHMO .

Biology and notes: The yellow larvae live freely in the capitula of Cirsium spp. ( Asteraceae). Infected capitula show little or no outward sign of damage. Our larvae were white, but this is likely because they were immature. DNA barcoding of one specimen placed it with Macrolabis .

Distribution: Known from several European countries including Norway and Finland.
