High-speed cameras have revealed the extraordinary hunting technique of the Australian ant-slayer spider, which is highly successful and thought to be unique
The ant-slayer spider of Australia has an extraordinary hunting technique that involves leaping over its much larger prey, high-speed photography has revealed.
While Aceves-Aparicio was at Macquarie University in Sydney, he noticed the unusual behaviour of ant-slayer spiders on trees on the campus at night.“I saw an ant climbing on the tree trunk, and I saw something happening really fast,” Aceves-Aparicio says. The spiders’ main prey is the banded sugar ant , which climbs eucalyptus trees after dusk to forage. The body length of the ants is twice that of the spiders.attaches itself to the trunk of the tree with a single silk line and then lies in wait for the ants, facing downwards. When an ant comes close, the spider jumps and use its hindmost pair of legs to attach the silk line to the ant – a move that takes less than a tenth of a second.
