The Power of Playing Dead A study shows that pretending to be immobile sometimes for an hour or more helps larvae of insects called antlions outlast hungry predators. An antlion larva, not actually dead.Credit.Nigel R. Franks By Cara Giaimo March 7, 2021 Antlion larvae are famously ferocious: They dig pits in the sand to catch unsuspecting prey, stab it with their sharp mandibles and digest it from the inside out. But everything is relative. To their own predators, antlion larvae are simply little snacks. And a colony’s cunning traps, grouped together and quite visible in the sand, are like flashing “DRIVE-THRU” signs. ....
Close Most animals fake death in order to escape from their predators, while some species of prey choose to remain motionless for a lengthy period of time. Charles Darwin documented a beetle that remained static for 23 minutes. Even so, the University of Bristol has recorded a single antlion larva feigning to be dead for an outstanding 61 minutes. (Photo : Egor Kamelev) Beast of Prey Equally, the number of times that an individual can remain static is unpredictable and not only long. This means that it will be difficult for a predator to predict when a prospective prey item will make a movement, thereby attracting its attention and becoming a meal to feed on. ....
blickwinkel / Alamy Playing dead might help prey animals stay alive because the tactic leaves predators vulnerable to having their attention diverted elsewhere. Nigel R. Franks at the University of Bristol, UK, and his colleagues were running a study on how the beetle-like larvae of flying antlions ( Euroleon nostras) use grains of sand to build pitfall traps to catch food. They noticed that when they dropped the 12-millimetre-long larvae onto a microbalance to weigh them, the insects would freeze.
