We examined differences in predatory behavior between two age groups (newly hatched spiders vs. spiders over 12 weeks old) of Yllenus arenarius Menge 1868 (Araneae: Salticidae). The spiders hunted three prey taxa (leafhoppers, caterpillars and thrips) for which they possess pre-programmed predatory behavior. The aim of the study was to check the influence of age and experience on pre-programmed predatory behavior and predatory success. Age-dependent changes occurred in four aspects of predation: direction of approach, mode of approach, distance of attack and predatory success.
