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.
Initially, the DuProprio application only featured properties for sale in a list, as it was not possible for a library to display Google Maps in a mobile app in 2009. In order to create what is now a commonplace experience for users, our team developed a custom MapKit based on Google Maps Web to display the tiles of the map. We also had to add our own implementation of touch handling and native positioning of properties, because internet performance on mobile devices was terrible at the time. This shows how incredible technological challenges are sometimes hidden behind the simplest user experiences.
A C. pallida female will find a spot for her nest. She will then dig diagonally down about 12 inches (30 cm). At the end of this tunnel, she will dig an 1 inch (2.5 cm) long vertical chamber where the egg will be laid. The chamber will be about 8 inches (20 cm) below the surface. In this chamber, the female will form a brood pot lined with wax. The brood pot will contain nectar and pollen similar to the bee bread in other bees; however, unlike other bees, the bee bread is the consistency of molasses instead of being solid. The egg is laid on top of the bee bread and sealed in with wax, and the tunnel is partially filled with dirt to protect the egg. A female can create several of the burrows during her lifetime.

This bee is black and densely covered in a grey pubescence or fur on the dorsal side. The thorax fur has a slightly yellow color. The legs have a mixture of black and reddish fur. The ventral side of the bee is covered in a brownish or dark yellow fur. The wings are fairly transparent except for the black veins that run through them. Males and females are similar in size at about 16–17 millimeters. Males have eyes more yellow in color, and their thorax fur is lighter. Females have eyes more green in color, and their thorax fur is more brown than grey.
L'unité de comparaison des prix de l'immobilier est généralement le prix au mètre carré (ou au pied carré, dans certains pays anglo-saxons). Pour les propriétés à revenus, on se sert de multiples du revenu et d'autres mesures reliées (taux d'actualisation). Enfin, des unités de comparaison fort variables sont aussi utilisées suivant le type de propriété (mètre cube, mètre de façade, prix à la chambre ou à l'appartement, etc.).
