The flight period of Caddis-flies (Trichoptera) on theIsland ofOsteroy, Western Norway.TROND ANDERSENAndersen, T. 1983. The flight period of Caddis-flies (Trichoptera) on the Island of OstemyWestern Norway. Fauna norv. Ser. B. 30.63-68.'The flight p~riod of 84 Trichoptera species are given, based on a collection of approximately75.000 specimens caught on the Island of Ostemy in outer Hordaland. The earliest speciestaken, Chilostigma sieboldi McLachlan, 1876, was flying in March. More species started tofly m May, and maximum number of speCies, 64, were taken in the beginning of August.Chaetopteryx villosa (Pabricius, 1798) was the latest species, flying until mid December.Rhy'ac~phila nl/hila (Zetterstedt, 1840) had the most extended flight period, starting in thebegmnmg of June and lasting until 20 November.Trond Andersen, Dept. of Systematic Zoology, Museum of Zoology, N-5000 Bergen, Norway.INTRODUCTIONRecords of the flight period of West NorwegianTrichoptera are sporadic and have mostly appearedin connection with faunistic surveys (Andersen1974, 1976, 1979, 1980a, 1980b, Andersenet al. 1978). Many of the Trichoptera foundin Western Norway are widely distributed andinformation on their flight periods in other partsof Europe can be drawn from the litterature. Inthis con<strong>text</strong> the flight periods recorded from~weden (e.g. Gbthberg 1970, Olsson 1971,Svensson 1972, Tobias 1969, Ulfstrand 1970)and from the British Isles (e.g. Brindle 1965,Crichton 1960, 1971, Crichton & Fisher 1981~richton et al. 1978, Hickin 1967) are of speciaimterest. Howe"er, a given species does notpecessarily have the same flight period in WesternNorway as in Sweden or on the BritishIsles. Crichton (I 97 I) and Crichton et al. (I 978)demonstrated that the flight period of most Trichoptera,with an extended flight period insouthern England, have shorter flight periods inScotland, and that many limnephilids flying inlate summer and autumn have their respectivemedian day, i.e. the day when 50 % of theyearly total have been caught, progressively laterwith lower latitudes.In the present paper I present flight periods ofmost West Norwegian Trichoptera, based oncollections made on the Island of Ostef0Y.STUDY AREAOstef0Y is a large inland island, with an area of328 km 2, situated northeast of Bergen in outerFauna norv. Ser. B. 30. 63-68. Oslo 1983~ordaland. The central and eastern parts of theIsland are mountainous, the highest point.H0gafjell, reaching 869 m a.s.!. The main featureof the topography in the western parts ofthe island is a series of low ridges passing in anorth-south direction.The island present a variety of freshwater localities.Along the coast and in the valleys in thewestern parts of the island there are a high numberof lakes and ponds with rich vegetation. Inthe cen~ral parts of the island there are marshyareas With ponds and small lakes vegetated withsedges and grasses, and even peat-bogs withsmall ponds. In the more central and mountainousparts there are also clearwater lakes withhardly any vegetation. Several smaller and largerstreams come running from the mountains,some fastflowing with coarse bottomsubtratumothers more slowly running with a finer sUbs~tratum. Several streams and small rivers flowthrough the lowlands in the western parts of theisland, most have stony bottom, but some havesandy or muddy substratum.Most of the field work was carried out in thewestern parts of the island. Streams, lakes andponds in the lowlands in this part of the island~ielded a high number of species. In a light trapsituated near a lake outlet a total of 64 specieswere taken. Lakes and ponds in the marshy andboggy areas in the central part of the island hada different fauna and yielded fewer species.Freshwater localities in the mountainous partswere also sampled. A light trap was situatedmore or less continuously for two seasons at arather fastflowing stream at 350 m a.s.l. The63
