'Accompanying' behaviour of Brachythemis leucosticta (Anisoptera: Libellulidae) in Europe: detailed description

Popis výsledku v původním jazyce

In southern Spain (Andalusia, near the town of Vejer de la Frontera -- Rio Barbate), observation was made of a local population of ca 40 individuals that had been determined to have an ability to accompany large mammals (the test subject was a human). The goal of the tests was to ascertain how far they are willing to accompany a large mammal, whether the size of the group has an influence on the distance for accompanying the subject, and whether the accompaniment differs between sexes. Accompanying a person was recorded in 53 cases, while this accompaniment was recorded for 41 males and 83 females. The dragonflies generally flew at a height of 10--50 cm above the ground, distributed in a semicircle with a radius of 1--2 m in front of the moving person(maximum observed group size was 11 dragonflies). Group size did not influence the flight range of the last individual or the detachment of the first individual from the group, as the dragonflies broke away at random. The average distance
