Biology and notes: The white larvae develop on the fungus Hypoxylon rubiginosum (Ascomycota: Hypoxylaceae ) on rotting logs of various deciduous trees. Each larva develops in an oval chamber made presumably of a mixture of fungal hyphae, frass and silk. The larva hibernates in the chamber and pupates there in the spring. The adult midge emerges by pushing against the cap of the chamber, which will often open like a hinged lid. This species has been encountered in Norway from time to time by mycologists but has not been officially reported from Norway until now. Here we report three records from 2012, 2020 and 2022 respectively. From one of the samples, which was collected in the autumn, we succeeded in hatching adults in the following spring. DNA barcoding was attempted on one adult specimen from this sample, but without success. The species is reviewed in Evans (1970) and Spooner (2010) . Distribution: Known from a few European countries including Norway , Sweden and Denmark . European part of Russia .
