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]

In early 2010, as Eton announced income growth of ten times for its first quarter of 2010 vs. 2009, president Danilo Ignacio stated that the company was in the planning stage to open the second BPO office.[6] In September of the same year, Ignacio announced that Eton had begun collecting bids from contractors for the actual construction of the second BPO office.[7]

The other category of behavior (the hoverers) uses a very different strategy that relies on the inherent limitations of the patroller strategy. Females won't have copulated with a patroller if they weren't found before emerging, or if they departed while the male that found them was fighting off a rival. The hoverers will wait either near plants that are close to emergence areas, regardless of whether the plants are flowering, or at flowering trees and shrubs well away from the emergence areas. These bees will hover anywhere from a few centimeters to eight meters in the air. Since patrollers are generally looking at the ground to find emergence areas, hoverers have less competition over escaped females. Those that are close to the emergence areas are able to quickly spot any females that got away from the patrollers. Male bees that are away from emergence areas stake out flowering plants in the hope that virgin females will arrive seeking food. Also, low-emergence areas are less likely to be patrolled, and thus, more females emerge without copulating.[9]


Situé à l’entrée du centre-ville de Québec au coin des boulevards Charest et Langelier, le projet propose un système de condos créatifs. Plus précisément, la construction de 86 modules individuels sur 5 niveaux qui seront répartis en 70 unités d’habitation. Selon les besoins exprimés par la clientèle, ces unités peuvent être aménagées en studios, 31/2, 41/2, 51/2 et 61/2 pièces et ce, en ayant la possibilité d'ajouter au module de base un demi module ou un module complet. Les futurs acheteurs peuvent donc créer leur espace de vie selon leurs besoins. Pour ce faire, nous utilisons un système structural hybride et novateur alliant le béton, l’acier et le bois massif dans leurs caractéristiques les plus performantes.
