The cobwebs? Old stuff! Some African spiders prefer to directly steal "mouth" food from ants. But the thieves have set up the cameras …

Would you rather eat a leftover dough left in the fridge for a few days, or a nice plate of freshly baked lasagna? Faced with similar food "dilemmas", jumping spiders (Gen. Menemerus) have no doubts: fresh food is much better! Yes, but procured by someone else.
A team of researchers from the University of Canterbury in Christchurch (New Zealand) filmed the behavior of some of these arachnids on the beaches of Lake Victoria in Kenya. Discovering that during the "lunch time", the crafty ones crouch to wait for the ants to re-enter the anthill loaded with tasty insects freshly caught.
Thanks to their natural qualities - a very sharp sight and the ability to jump from one place to another using the thread of the web as if it were a liana - they swoop on unsuspecting fomics by stealing their meal. Thus with little effort the small thieves (no longer than 6 millimeters) remedy succulent and above all fresh flies.
Much more digestible than the dried insects left in the canvases (find out how a jumping spider's web is made) .
