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.[6]

The genus Centris contains circa 250 species of large apid bees occurring in the Neotropical and Nearctic regions, from Kansas to Argentina. Most females of these bees possess adaptations for carrying floral oils rather than (or in addition to) pollen or nectar. They visit mainly plants of the family Malpighiaceae to collect oil, but also Plantaginaceae, Calceolariaceae, Krameriaceae and others. Recent studies have shown they are sister to the corbiculate bees, the most well-known and economically important group of bees [1]

The egg will then hatch within two weeks, and the grub will eat the nourishment that the mother left. The amount of bee bread provided will directly affect the size of the offspring (more food = larger size). When the food has been eaten and the grub has fully developed, the grub will turn into a prepupa. Over the course of eleven months, the prepupa will undergo metamorphosis to become an adult bee. The adult bee will then dig to the surface in late April or early May, and will live for about a month. By late July, virtually no C. pallida can be found.[7]


"Homes are selling faster and faster in the Montréal area, as the average selling time, for all property categories combined, was 80 days in November, which is seven days less than one year ago," said Nathalie Bégin, President of the GMREB board of directors. "Single-family homes and plexes sold the fastest – in an average of 72 days – while it took an average of 94 days for a condominium to sell," she added. 
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.[13]
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]

Un arpenteur-géomètre professionnel a la tâche de localiser l’emplacement de votre maison sur votre terrain. Ce certificat permet à la municipalité et à l’institution bancaire de s’assurer de la conformité des marges de recul, avant, arrière et latérales. Ce document pourra aussi vous assurer qu’il n’y aura pas de chicane de « clôture » avec vos voisins lors de l’installation d’une haie, d’une remise ou même d’une piscine ou d’un spa.
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.

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.).
