Desert birds and lizards are predators of C. pallida, and these bees can be parasitized by the meloid beetle (Tegrodera erosa); however, rain is the largest threat to these bees. At night and during the heat of the day, C. pallida bees will hide under rocks, trees, in burrows, etc. When it rains, the bees can get wet. If the bee is in a burrow, it may simply drown. If the bee is underneath something, when night comes, the bee may freeze to death due to the low temperatures in the desert. Since these bees are solitary, they don’t have the protection of a hive or colony; thus, they are more susceptible to the elements.

The other category of behavior (the hoverers) uses a very different strategy that relies on the inherent limitations of the patroller strategy. Females won't have copulated with a patroller if they weren't found before emerging, or if they departed while the male that found them was fighting off a rival. The hoverers will wait either near plants that are close to emergence areas, regardless of whether the plants are flowering, or at flowering trees and shrubs well away from the emergence areas. These bees will hover anywhere from a few centimeters to eight meters in the air. Since patrollers are generally looking at the ground to find emergence areas, hoverers have less competition over escaped females. Those that are close to the emergence areas are able to quickly spot any females that got away from the patrollers. Male bees that are away from emergence areas stake out flowering plants in the hope that virgin females will arrive seeking food. Also, low-emergence areas are less likely to be patrolled, and thus, more females emerge without copulating.
