in middle ofApril and adults are also found inlate autumn, and hibernates as imago. H.stigma may be bivoltine in the lowlands andunivoltine at Dovrefjell. Similar conditionsfor other species are found in middle Europe(Gepp 1975). The specimens of the only megalopterancaught, S. lutaria, was from 25June to 9 July. S. lutaria is the only species ofSialis common in southern and central Norway.S. lutaria was also caught in similarbiotops at Hardangervidda (Greve 1976),between 4 July and I August. The highestlocality at Hardangervidda was at Normannslagenat 1243 m a.s.1. and thus in thelower alpine zone. The flight period is delayedin montainous areas compared with lowlandpopulations (Andersen & Greve 1975,Kaiser 1950), a phenomenon well knownfrom other insect groups.The populations of all species seem to besmaller than in the lowlands, though for somelike W. mortoni, this conclusion cannot bedrawn. The flight period of some species isdefinitely more restricted in the mountainsthan in the lowlands. As predators, they certainlytake their toll among Aphididae andmites, well known food animals for the larvae,but since their size is rather small, theyprobably are not important as food for otherinvertebrates, fish (Sialis lutaria larvae only),birds or mammals.ACKNOWLEDGEMENTSSupports to the field work of this paper hasbeen given by The Norwegian Research Councilfor Science and the Humanities, grantnos.

Fauna norv. Ser. B, 34, 63-72.In the mountains of Dovrefjell National Park, South Norway, we collected 4S spp. offam. Limoniidae in Malaise traps in the years 1980 to 1983. Dicranomyia incisurataLackschewitz is reported new to the Scandinavian fauna, and Dicranota (Paradicranota)robusta Lundstrom, Ufa mollissima Haliday and Symplecta scotica Edwards newto the Norwegian fauna. The collecting covered the subalpine, low and middle alpinezones. The dominant species Phyllolabis macroura Siebke, made up S1.4% of theindividuals in the subalpine zone, and 72.6% in the low alpine zone (1080-1400 ma.s.!. ).From zoogeographic aspects, the species list from Dovrefjell is compared withspecies lists from four other Scandinavian areas. Of the 45 species collected aJ Dovrefjell,29 were in common with species from Varanger, North Norway, 24 with Angeran,Sweden, 33 with Messaure, Sweden, and 37 with Tornetriisk, Sweden. The montaneareas Tornetriisk and Dovrefjell, showed greatest similarity in species composition.Data on phenology and notes on 10 species are given.Hans Mendl, Johann-Schiitz-Str. 31, D-8960 Kempten/Allg., BRD.John O.

On the eastern side isthe Trondheim region, which contains mainlymedium-grade mica schists and greenstonesof the cambro-silurian age. The western sideis mainly basal gneiss region build up ofhighgrade gneisses and schists of precambrianage. The differences in the geology are mostconspicuous when plants are considered. Theeastern side has a much higher diversity ofplant species than the western one. The samplingsites Stropla, Kallvella and Gluptjern(Tab. 1) are on the western side, and theremaining on the eastern. The streams andlakes in the Stropla area have pH in the range6.0 to 6.5, and the lake Kallvellsj6en is aboutpH 6.8.

This paper deals with thespecies distribution, abundance, flight periods and zoogeographic views of the Limoniidae. The limoniids are poorly known inNorway. Mendl & Solem (1972) mentionedonly very few papers dealing with the Limoniidaein Norway. The same conclusion canbe drawn today too. Since 1972, only oneadditional paper has reported on NorwegianLimoniidae (MendI 1984).STUDY AREA AND METHODSThis study was conducted in the DovrefjellNational Park, South Norway, where theKongsvoll Biological Station is located (62°ITN, 09°59'E, see Fig. 1).
