In the Sahara, ants live where no bushes or clumps of grass are available to protect them, and where tracks are covered by wind-blown sand in seconds. The midday sun is so hot that even the permanent residents, sand lizards, insects, and a few birds, have to take shelter, but this is when, for not much more than an hour,
Cataglyphis spp. are to come out of their underground nests and forage. They can withstand higher temperatures than any other insects. They pour out on to the sand and search for insects that have died of heat stress. Each ant dashes about in zigzag patterns, but as soon as one is lucky enough to find a tiny insect corpse, it has to get it back to the nest quickly before the ant dies of the heat. It does not retrace the zig-zagging path of its outward journey; even if a scent trail made this possible, such a route would be time-wasting. Instead, it runs in a straight line directly back to its nest hole. Cataglyphis nigra-lateral.jpg|
