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.
Centris pallida serve numerous roles for the environment. Like most other bees, they are essential for pollination. Specifically, they pollinate cacti, desert willow, and palo verde. The tunneling ability of these bees aerates the soil, and this allows water from rain to reach plant roots quickly. Their nitrogen rich feces fertilizes the soil. Their stings are mild, so they are not dangerous. The only downside with respect to humans is that their burrowing can leave unsightly mounds. If an area has a large density of burrowing females, then these mounds can be quite noticeable and are difficult to get rid of.
Centris pallida typically feed on flowers that can withstand the hot temperatures of its habitat. These plants include palo verde (Cercidium microphyllum and Cercidium floridium), ironwood (Olnyea tesota), and creosote bush (Larrea divaricata). The palo verde pollen is the most common, and it gives the bee bread a strong orange color. Due to the large expenditure of energy by males during hovering and/or patrolling, they must consume about 3.5 times their body weight in nectar each day.
Four varieties of bacteria have been found in the bee bread of the larva: Bacillus circulans, B. coagulans, B. firmus, and B. megaterium. Only the Bacillus genus has been found in the samples taken. Together, these four species were able to hydrolyze starch, ferment glucose, convert nitrates to nitrites, and produce dihydroxyacetone from glycerol. This group of bacteria also lowers the pH of the bee bread. These functions serve not only to protect the larva from other bacteria, but they also digest complex molecules which allow the larva to easily absorb nutrients without expending a lot of energy. The bacteria, in turn, receive a supply of food which results in a mutualistic relationship.
On parle de vente « immobilière (date de création 1920) » lorsque la vente porte sur un bien immobilier. Ne sont normalement compris dans une vente immobilière que les éléments immobiliers. La vente des biens mobiliers doit être réalisée de manière indépendante. En droit, on considère aussi qu'il existe des objets meubles1 qui peuvent devenir immobiliers.
Chaque propriétaire d'une résidence du projet Carré Mi-Vallon, s'engage à planter au moins un arbre par deux cents mètres carrés (200,0 m. car.) de superficie de terrain acquis, dont un arbre doit obligatoirement être en façade de la résidence. 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.
