Dynastinae is a subfamily of beetles commonly known as rhinoceros beetles. They are characterized by their large size and distinctive horns, which are often used by males during fights for mating rights. These beetles can be found in various habitats, including forests and grasslands, and are primarily active at night. Rhinoceros beetles are known for their impressive strength, capable of lifting objects many times their own weight. They feed on decaying plant material, contributing to nutrient recycling in their ecosystems. The larvae of Dynastinae develop in rotting wood or compost, further aiding in decomposition processes.
