shown to be common in many European fields (Tischler 1958, Geiler 1959/60). Maximum activity occurred in June - July (Fig. 17), when it probably reproduces. From 18. Aug,-29. Sept. callow Tachyporus-specimens belonging to the next generation were caught. As shown by Lipkow (J 966) this generation probably overwinters and reproduces the next summer. The separately treated eight carabid species together with Peterostichus niger (Schaller), Amara apricaria (Paykull) and Harpalus affinis (Schrank) were those caught in all the fields or all but one, making op 87.7 % of the carabid material. For the staphylinids, the same holds for the eight separately treated species together with Tachyporus chrysomelinus (L.), Aleochara bilineata (GyllenhaO, Philonthus cognatus (Stephens), Tachyporus obtusus (L.), Philonthus carbonarius (Gravenhorst) and Acrotona aterrima (Gravehorst), making up 87.4 % of the material. Most of these 25 species are frequently mentioned as common in other European fields and may be regarded as the common field species in the investigated area. In addition, some species were common at only one or two of the localities. The carabid Agonum dorsale (Pontoppidan) made up 6.7 % of the catch at Je10Y, and was only trapped here (Tab. 1l. This species is rare in Norway, Je10Y being one of the few places where it is known to occur (Kvamme 1977), though common in other European fields (Nedstam & Johansson 1974, Thiele 1977). Amara fulva (Degeer), a carabid strongly preferring dry sandy areas (Lindroth 1945), was only trapped at Je10Y (Tab. 0, while Bembidion guttula (Fabricius) and Trechus secalis (Paykull) were mainly caught at As, as they are known to prefer clay (Lindroth 1945). The staphylinid Tachinus corticinus (Gravenhorst) was for some unknown reason very common at Jel0Y in 1971, but otherwise a rare species (Tab. 1). In the Oxypoda-material the following species were common at Jel0Y in 1976 and may dominate in the unclassified material in the rest of the fields as well: O. bracyptera (Stephens), O. haemorrhoa (Mannerheim) and O. advena (Miiklin). At least O. brachyptera is reported from other fields (Geiler 1959/60, Topp & Trittelvitz 1980). Aleochara spadicea (Erichson), A. verna (Say) and Quedius nitipennis (Stephens) are new to 0stfold county. As shown in Figs. 2- 17 the activity density of a species might vary considerably from one year to the next i.n the same locality, often as much as a 10-fold increase or decrease. As a resuit both the dominating species and the whole beetle fauna in each locality varied a lot from year to year. However, a species dominating one year was usually among the more abundant species all years in the same locality. In this way the same few species would make up a large part of the fauna in the locality each year although their relative importance would change from year to year. ACKNOWLEDGEMENTS I am very grateful to Dr. L. S0mme and T. Rygg for their valuable advice during the investigation, Dr. S0mme also for criticizing the manuscript. I also wish to thank cand. real. A. Fjellberg for classifying parts of the material in 1975 and 1976 and A. Taksdal for correcting my English. The investigation was financially supported by the Norwegian Agricultural Research Council (NLVF). REFERENCES Basedow, Th., Borg, A., Clercq, R. de. Nijveldt, W. & Schemey, F. 1976.
