They are large (up to 3 cm), fast-flying bees, distinguished from the closely related genus Epicharis by the absence of long, whip-like setae that project backwards from just behind the eyes. They are commonly encountered bees in American deserts, and are active at very high ambient temperatures when many other species are in hiding. They can often be seen in large numbers on desert-willow (Chilopsis) and palo verde (Parkinsonia) blossoms. Bees of this genus are of some economical significance in pollinating crops such as Brazil Nut (Bertholletia excelsa) and Cashew (Anacardium occidentale, pollinated by C. tarsata among others).

Apple released three computers bearing the Centris name: the Centris 610 (replacing the Macintosh IIsi) and Centris 650 (replacing the Macintosh IIci in form and the Quadra 700 in function), both of which were introduced in March 1993, and the Centris 660AV which followed in July. Apple also considered the Macintosh IIvx to be part of the Centris line. The IIvx was released in October of the previous year, but, according to Apple, their lawyers were unable to complete the trademark check on the "Centris" name in time for the IIvx's release.
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).

Tout d'abord, il faut savoir que l'eau des éclaboussures ne provient pas des conduites d'égout de la rue mais bien des siphons (trappe d'odeur : tube recourbé en forme de « S », placés à la sortie des appareils sanitaires, de façon à empêcher la remontée des mauvaises odeurs provenant de l'égout) de vos différents appareils sanitaires (toilette, évier, drains de plancher). De plus, vous pouvez remédier rapidement à ces inconvénients en ajoutant un peu d'eau dans les siphons de vos appareils et en ventilant bien la maison. Tout reviendra à la normale.
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. 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. 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.
