Description Mole crickets vary in size and appearance, but most of them are of moderate size for an insect, typically 3-5 cm long. They are muscular, as one may verify by holding one in the hand, they are inoffensive, but the confined insect will try to dig its way out with considerable force. The abdomen is rather soft, but the head, forelimbs, and pro-thorax are heavily sclerotic. The hind legs are shaped somewhat like the legs of a real cricket, but are more adapted for shoving while digging, rather than leaping, which they do rarely and poorly Biology Most species of mole crickets can fly powerfully, if not with agility or frequency. Usually they fly only when moving long distances, such as when changing territory. The adults of some species of mole cricket may fly as far as 8 kilometers (5.0 mi) during the mating season. Mole crickets are active most of the year, but spend the winter in hibernation. Younger insects can have shorter wings, and their appearance varies by species, with some resembling grasshoppers or very large ants or dark-colored "termites" when wings are short. Mole crickets are omnivores, feeding on larvae, worms, roots, and grasses. Common predators of mole crickets include birds, rats, skunks, armadillos, raccoons, foxes and blue ants. Mole crickets are relatively common, but because they are nocturnal and spend nearly all their lives underground in extensive tunnel systems, they are rarely seen. Mole crickets amplify their song by chirping in a burrow that they've carefully sculpted into the shape of a double exponential horn, which acts as a megaphone. They inhabit agricultural fields, lawns and golf courses. They are present in every continent with the exception of Antarctica, and are commonly considered pests. |
