Evidence for woodlice-specialization in Dysdera spiders: behavioural versus developmental approaches

Original language description

The dietary specialization in a woodlouse-eating spider Dysdera hungarica Kulczynski (Araneae: Dysderidae) is studied using two types of laboratory experiments. In the first experiment, the rate of development of spiderlings reared on one of three diets:pure woodlice [composed of two species Oniscus asellus Linnaeus and Armadillidium vulgare (Latreille)]; pure flies ( Drosophila melanogaster Meigen); and a mixed woodlouse-fly diet, is studied. Spiders develop significantly faster on the woodlice-containing diets (i.e. pure woodlice and mixed diet) than on the fly diet. In the second experiment, the prey-choice for two woodlice species ( O. asellus and A. vulgare ) and a fly ( D. melanogaster ) is investigated. Dysdera hungarica spiders capture significantly more often flies than woodlice. These contrasting results reveal the different value of developmental and behavioural experiments. The dietary studies are assumed to provide better evidence of specialization than behavioural experi
