Centris pallida was officially discovered and catalogued by William J. Fox in 1899 near Phoenix, Arizona.[1] Fox also discovered Centris cockerelli, Centris errans, and Sphex subhyalinus. This species is closely related to Centris cockerelli in terms of habitat and genus, but is different in terms of mating, color, and subgenus.[2] This bee also belongs to the superfamily Apoidea, and the subfamily Apinae.[1]
Centris pallida typically feed on flowers that can withstand the hot temperatures of its habitat. These plants include palo verde (Cercidium microphyllum and Cercidium floridium), ironwood (Olnyea tesota), and creosote bush (Larrea divaricata).[9] The palo verde pollen is the most common, and it gives the bee bread a strong orange color.[7] Due to the large expenditure of energy by males during hovering and/or patrolling, they must consume about 3.5 times their body weight in nectar each day.[10]
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]
The process of integrating the province’s various Centris databases began approximately five years ago and was completed in June 2008. All transactions concluded through a real estate broker who is a member of a real estate board are added to the new provincial database. The Québec Federation of Real Estate Boards (QFREB) uses this database to publish press releases and other publications on market conditions, including the Centris Barometer – Residential Market, which provides an overview of key performance indicators associated with the resale market (i.e., sales, new listings, median prices, number of days on the market, etc.). These indicators are calculated according to consistent, stringent rules so that statistics can be comparable across geographic areas.
