They are large (up to 3 cm), fast-flying bees, distinguished from the closely related genus Epicharis by the absence of long, whip-like setae that project backwards from just behind the eyes. They are commonly encountered bees in American deserts, and are active at very high ambient temperatures when many other species are in hiding. They can often be seen in large numbers on desert-willow (Chilopsis) and palo verde (Parkinsonia) blossoms. Bees of this genus are of some economical significance in pollinating crops such as Brazil Nut (Bertholletia excelsa) and Cashew (Anacardium occidentale, pollinated by C. tarsata among others).

Il est déconseillé d'utiliser une vadrouille mouillée. Favorisez plutôt l'usage de l'aspirateur ou du balai. Les liquides précipitent l'usure du plancher et peuvent endommager le fini. Afin de nettoyer les éclaboussures, utilisez un linge légèrement humide. Un nettoyage hebdomadaire est conseillé afin d'éviter l'accumulation de dépôts de poussière.

L’essence de cet arbre est laissée à la discrétion de l’acheteur. Cependant les arbres devront avoir une circonférence de 1 ½ pouce minimum et une hauteur minimale se situant entre 6 et 8 pieds.
Male C. pallida are able detect the pheromones which females release and use them to locate female burrows. When a virgin female is about to emerge from her burrow, she releases a scent that wafts up through the soil and is detected by the antenna of the males. This has led to males developing a very acute olfactory sense. Freshly-killed females have been buried to test whether sound also plays a part in male signaling. In these tests, male bees still dug up the dead females, proving that pheromone signaling is the only pathway. Males have also been observed to dig up other males. This shows that males and virgin females give off similar pheromones. Oddly, males also sometimes dig up other digger bee species. It is currently unknown why this occurs.
