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 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]

Desert birds and lizards are predators of C. pallida, and these bees can be parasitized by the meloid beetle (Tegrodera erosa); however, rain is the largest threat to these bees.[12] At night and during the heat of the day, C. pallida bees will hide under rocks, trees, in burrows, etc. When it rains, the bees can get wet. If the bee is in a burrow, it may simply drown. If the bee is underneath something, when night comes, the bee may freeze to death due to the low temperatures in the desert. Since these bees are solitary, they don’t have the protection of a hive or colony; thus, they are more susceptible to the elements.[11]
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]

1ere coupe : courte : 3,5 cm. Augmenter progressivement à 7,5 cm. Si la pelouse est faible : tondre à une hauteur de 7 à 10 cm. On peut tondre plus fréquemment car la pelouse pousse plus rapidement. Tondre à 7,5 cm tout l'été. Coupes moins fréquentes en périodes chaudes. En période de canicule, il ne faut pas couper plus court que prévu : 7,5 cm. Tondre jusqu'à ce que la température baisse et que l'herbe pousse moins rapidement. Diminuer alors la hauteur de tonte de 7,5 cm à 3,5 cm, jusqu'à l'arrêt de la croissance. On peut tondre plus fréquemment car la pelouse pousse plus rapidement.

There is a size correlation which determines whether males become patrollers or hoverers. Patrollers tend to be larger so that they can better protect and copulate with emerging females. Smaller males are usually unable to compete as well, and so have to make the best out of a bad situation; thus, they become hoverers. Each group has a different set of behaviors. The patrollers move over a large space containing many other patrollers. Usually, patrollers will frequent the same spots over the course of their lives. Since the area is so large, the cost to defend it against other patrollers would be much greater than the potential mating benefits, so the patrollers show very little territoriality.[11] Patroller males will usually only fight when a breeding female is near. In contrast, each hoverer stakes out an area of about one meter in diameter. These areas don’t overlap with other hoverers. Any fast moving object (i.e. bee, dragonfly, leaf, etc.) that enters a territory will be quickly chased. The chase allows the male bee to determine if a female is unmated, or if an enemy male is in his territory. If it is a male bee, the territory owner will chase it out, but not beyond the boundary of the territory. What is interesting is that every day (or even every several hours) the territory holder will abandon the area to establish a new zone. Often the male will never return to the vacated area, and it will be taken over by another male. This shows that hoverers show a low site tendency but strong territoriality.[11] A balanced ratio of patrollers to hoverers is maintained, and thus, this ratio is an evolutionary stable strategy. If more males become patrollers, then the hoverers will benefit from the reduced competition, and the hoverers' genes will spread until the stable ratio is returned to. The same thing will happen if more males become hoverers.
Ceux qui préfèrent un environnement tranquille se plairont à Québec. On peut trouver un parc à une certaine distance de la majorité des maisons et les résidents peuvent compter sur la présence de quelques centaines d'espaces verts publics, comme par exemple la Base de plein air de Sainte-Foy et le Parc des Champs-de-Bataille, ce qui fait qu'ils sont faciles d'accès. La ville plaira également à ceux qui préfèrent les environnements silencieux, étant donné qu'il y a peu de bruit lié à la circulation automobile - même si plusieurs secteurs de la ville sont plus bruyants, comme par exemple près de l'une des 3 voies ferrées, de l'Autoroute Félix-Leclerc, de l'Autoroute Henri-IV ou de l'aéroport (YQB).  Quebec - Lire davantage à propos des propriétés à vendre dans cette région
