| Abstrakt: | Abstract: a_1Thirty-eight species of the subfamily Cecidomyiinae were found during investigations in 1995 around Harstad in northern Norway and 56 species in 2003 around Trondheim in central Norway, altogether 73 species of which 46 are new records for Norway. The present fauna of gall midges of the family Cecidomyiidae of Norway includes 238 species of which 119 species in 37 genera belong to Cecidomyiinae, 4 species to Porricondylinae, 109 species to Lestremiinae and 6 are unplaced species. An annotated list of species of the subfamily Cecidomyiinae and a list of host plants and associated gall midges is given. Zoogeographical analysis: 51% are European, 23% Euro-Siberian, 15% Euro-Asian, 8.5% Holarctic and 2.5% alien species. Harstad, about 300 km north from the Arctic Circle, is for 38 species the most northern situated known locality of distribution area in Europe. Frequency: 42% species occur very scarcely, 18.5% scarcely, 28% medium frequently, 8.5% frequently and 3% very frequently. Dasineura tortilis (Bremi, 1847) causing leaf galls on Alnus incana (L.) Moench, Dasineura ulmaria (Bremi, 1847) on leaves of Filipendula ulmaria (L.) Maxim. and Oligotrophus juniperinus (Linnaeus, 1758) on branches of Juniperus communis L. are very frequent. Iteomyia capreae (Winnertz, 1853) inducing galls on leaves of Salix caprea L. and other Salix-species is the most frequent species occurring in Norway. |
