Warm-season lawn, particularly those with heavy thatch.
Cricket-like in shape but has mole-like, digging front legs. Two Oklahoma species, Northern mole cricket and Prairie mole cricket, are found mostly in the eastern 2/3 of the state. They spend most of the year burrowing just below the surface of the soil and are active above ground in April and May in Oklahoma for mating and dispersal flights.
Mole crickets use huge claws on their forelegs to dig through the lawn and soil surface, uprooting large patches of grass. They feed on plant roots, insects, and decaying organic matter.
For prevention, avoid heavy watering and fertilizing, and dethatch the lawn as needed.
