Contarinia quinquenotata (F. Löw, 1888)

Material: AK, Oslo: Tøyen, Botanical Garden, 59.918752°N 10.771581°E ± 20m, 24 June 2019, on Hemerocallis lilioasphodelus, LMF, leg. HE, coll. NHMO.

Biology and notes: The white to pale yellow larvae develop gregariously in galled flower buds of Hemerocallis fulva ( Asphodelaceae). Our record is from H. lilioasphodelus, which represents a new host plant. Infected buds do not open and become swollen and disfigured. Univoltine; pupation and hibernation in the soil. This species is alien in our region. Skuhravá & Skuhravý (2012) first reported it from Norway based on material collected from Hemerocallis fulva in Stjørdal i 2003.

Distribution: Native to Asia. Widespread in Europe including Norway, Sweden and Denmark. Introduced to New Zealand and the Nearctic.
