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.
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.[7] 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.[8] A female can create several of the burrows during her lifetime.
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.
