Can solitary spiders (Araneae) cooperate in prey capture?

Popis výsledku v původním jazyce

Cooperation in prey capture has never been reported for a solitary spider. Here, we conducted a laboratory experiment to determine if group hunting occurs in the ant-eating Zodarion spiders and if it yields higher individual benefit than solitary prey capture. Spiderlings of the second instar were kept in groups of 1, 3 and 6 individuals. Their foraging behaviour was studied with two ant species as prey: a large Messor and a small Tapinoma. Groups of 3 and 6 spiders had better capture success than a single individual. The paralysis time of Messor was reduced as the number of spiders in a group increased while that of Tapinoma ants was similar for all group sizes. The feeding time on Messor increased with the number of spiders in a group, even all 6 individuals could feed simultaneously. For Tapinoma ants, 6 spiders fed significantly shorter than the group of 3 spiders due to more intraspecific interactions. Only 1-2 spiders fed on Tapinoma at the same time. For spiders feeding on Messo
