Just a relatively small group of larvae is capable of completely destroying a pizza in less than two hours.
A group of scientists put thousands of larvae together and discovered that one group eats for five minutes before resting and letting others take over.
Black fly larvae allow the other larvae to take over when they have finished feeding.
Despite the fact that the footage of the experiment, published by the Royal Society, seems a bit chaotic, the insects are actually very organised.
The video above shows the results of their experiment.
