Yes, this fox eats insects, with termites making up to 70 percent of its diet. Besides termites, which it licks up from the ground, the bat-eared fox eats dung beetles and their larvae, grasshoppers, scorpions, spiders, millipedes, rodents, lizards, fruits, and eggs. But insects make up the main part of its diet.
Bat-eared foxes have more teeth (46 to 50) than most mammals, and that's what sets them apart from other fox species. While other members of the dog family have two upper and three lower molars on each side of the mouth, bat-eared foxes have three upper and four lower molars. Specialized teeth chew their creeping, crawling food, and those huge ears can listen for insects moving around.
Can you hear beetles crawling? Bat-eared foxes find prey by walking slowly with their nose close to the ground and ears cocked. Once they locate the insects by sound, the foxes jump or dig quickly to catch them and crunch them up for a tasty, high-protein meal. Bat-eared foxes hang around hoofed animals, because from those animals comes poop—and insects come buzzing around the droppings, providing a ready feast for the foxes. These little canids sometimes travel up to 7.5 miles (12 kilometers) each night when looking for food.
Bat-eared foxes at the San Diego Zoo and San Diego Zoo Safari Park receive a fortified meat-based commercial carnivore diet, dog kibble, a small mouse, mealworms, and crickets. Keepers say mealworms are their favorite—like fox candy!
