The two categories of behavior for C. pallida males are patrolling and hovering. These strategies are also used to find mates. In one category (the patrollers), male bees will patrol 3–6 centimeters above the ground in search of sites where buried virgin females will emerge. When a male bee finds such a site, he will dig 1–2 centimeters through the soil by gnawing at the surface with his jaws and using his forelegs to remove dirt from the excavation. If a female is found, he will attempt to mate with her either on the surface or at a nearby flower or tree. Other patrollers will sometimes attempt to steal a digging spot that another bee has found. If a bee has already found a female, another patroller bee may separate the male from the female so that it can copulate with the virgin. More often than not, the female (once found) will mate with either the male that found her or with an intruder.[6]

“The number of condominiums for sale in the Greater Montréal area fell by about 22% in May. A drop like this has not been seen in nearly 15 years,” said Mathieu Cousineau, President of the GMREB Board of Directors. “With strong demand and a decrease in supply, as we have been seeing for several months now, the condominium segment – against all expectations – is on the verge of moving into a seller’s market too,” added Mr. Cousineau.

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.[14] 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.[15] 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.[14]
Centris pallida is a species of solitary bee native to North America. It lacks an accepted common name; however, it has been called the digger bee, the desert bee, and the pallid bee due to its actions, habitat, and color respectively. The solitary nature of this bee allows for a dual-strategy mating system which produces an evolutionarily stable state resistant to invading strategies. These bees have also evolved to withstand the high temperatures of their native habitat. C. pallida routinely has internal temperatures within 3 degrees Celsius of death.
Le patrimoine architectural de Québec comprend l'ensemble des bâtiments de l'Assemblée nationale qui ont été érigés sur la colline Parlementaire à partir de 1877. On y retrouve deux styles architecturaux, soit le style Second Empire pour l'Hôtel du Parlement et l'architecture Beaux-Arts pour les autres édifices. La Citadelle de Québec, construite entre 1820 et 1831, le Château Frontenac, bâti entre 1892 et 1893, et la Terrasse Dufferin font également partie du site patrimonial du Vieux-Québec.
