This is the case for the species Anelosimus eximius – small red spiders, native to Central and South America. They live in colonies of up to thousands of individuals and work together to build giant webs that span several meters.

When an insect (like a moth or a grasshopper) gets curled up in the web, the colony begins a synchronized attack: the spiders move towards the prey, at the same time, stopping the race a few times to ensure that they all arrive together. destiny. (You can observe the behavior in this video).

Thus, spiders are able to capture prey that is up to 700 times heavier than themselves – a better meal than could be obtained in a solo attack. But it was not yet clear how individuals of the species combine their movements.
