Abstract

A population of the microphthalmic carabid beetle Laemostenus schreibersi Küster 1846, was studied in a cave near Villach in Carinthia during eight periods of investigation (from 1986 to 1988 and in 1990 and 1992). The beetles were trapped in pitfalls, individually marked and released in the cave near the trapping site. Obviously, in some seasons all individuals living inside the explored cave-compartments were marked. The size of the population was small, but rather constant (80–100 individuals). Longevity of the individuals is discussed as a factor stabilizing population size. Other aspects investigated in this paper deal with: spatial distribution and patterns of movement inside the cave, seasonality of breeding and development, sex-ratio. Measurements of climatic parameters complemented the biological investigations.
