Abstract
476 individuals of Carabus glabratus were collected in the years 1989-90 with pit-fall traps in the Väniötunturi fell terrain in NE Finland. The catch in 1990 was about twice as great as in the previous year. The tertiary sex ratio was even. The main habitat was Scots pine forest 370 m a.s.l., but the species also occurred in abundance in the mountain birch forest zone, in spruce forest, on a Nardus stricta sloping fen and on the shore of Lake Kuutsjärvi, whereas the treeless summit of the fell was almost totally avoided. The main activity period was at the end of June and the beginning of July, the males occurring over a shorter period. Daily catches closely followed the temperature curves.
