Mole crickets are roughly 3-5 centimeters long with wings and large front legs that they use to dig in soil. Most though not all species are able to fly for short distances. Mole crickets lay their eggs in the tunnels they make underneath the soil. They are nocturnal and are omnivores meaning that they eat worms and larvae as well as grass. In cold weather, mole crickets hibernate and they are generally at their most destructive from August through October.
