Movement patterns of Carabus hortensis Linnaeus, 1758 (Coleoptera, Carabidae) in a pine and a beech forest

Walking distances, turning angles, turning to the left and the right, and preferences concerning direction of the compass of individuals of Carabus hortensis Linnaeus, 1758 were studied in a pine forest and a beech forest using a portable harmonic radar system. No significant differences concerning the first three above mentioned characteristics could be detected. In contrary, a significant difference with respect to the distributions on the four directions of the compass exists between the forests. In both forests north and west are the preferred directions, but a higher preference of the south was observed in the beech forest when compared to the pine forest.
