Asian Weaver ants (Oecophylla smaragdina) can carry weights of more than 100 times their own body weight whilst upside down on a smooth surface. To do this, they have incredibly sticky pads on their feet.
However, this does not stop them from running quickly across such surfaces. Research has revealed how they cope with the conflict of sticking to a surface but not getting stuck.
Weaver ants are known for building nests using leaves woven together with silk. They are very territorial and their tendency to defend against intruders can make them a useful tool in controlling agricultural insect pests, avoiding the need for chemical insecticides.
They have traditionally been used in this way in Chinese and Southeast Asian citrus orchards for at least 1,500 years.
