  Range Caterpillar, Range Caterpillar Moth

  Hemileuca oliviae, the range caterpillar, is a day-flying saturniid moth native to grasslands of the southwestern United States and northern Mexico. The species is notable for periodic population outbreaks that can cause significant damage to rangeland vegetation, impacting forage availability for livestock. Its distribution is restricted to open grassland habitats due to predation pressure from woodland rodents on eggs and pupae. The moth has been studied extensively for its ecological interactions, including host plant relationships, water physiology, and natural enemy complexes.
