The larvae have a diverse diet and have been recorded feeding on Astragalus canadensis and Cirsium lecontei. They have also been recorded as internal feeders in cat-tails (Typhus species) and cactus stems (Opuntia species). Furthermore, they feed on senescent cotton bolls (Gossypium species) and are also known as predators on the eggs and larvae of Thyridopteryx ephemeraeformis.
