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).

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 Centris 610 and 650 were replaced about six months after their introduction by the Quadra 610 and 650 models, which kept the same case and designs but raised the CPU speeds from 20 MHz and 25 MHz to 25 MHz and 33 MHz respectively; while the Centris 660AV was renamed to Quadra 660AV without any actual design change. These Macs also existed during Apple's transition from auto-inject floppy drives to manual-inject drives.[4] This is why there are two different styles of floppy drive bezel (faceplate) on these models. Some later Centris 660AV Macs have manual-inject floppy drives, so this change was not exactly concurrent with the name change.

Centris pallida are able to withstand very high internal temperatures when compared to other bees. Males regularly have thoracic temperatures of 48 to 49 degrees Celsius (118.4 to 120.2 degrees Fahrenheit). If the thoracic temperature reaches 51 to 52 degrees Celsius (123.8 to 125.6 degrees Fahrenheit), the bee will become paralyzed and die. Most of the cooling occurs when heat radiates off the abdomen. To prevent overheating, C. pallida have a very high thoracic conductance (rate of heat transfer from the thorax to the abdomen) which is 45 percent higher than that of sphinx moths of the same size. Other than this high thoracic conductance, no other mechanism has been found to help the bee reduce its internal temperature. C. pallida do not appear to have evaporative cooling in the wild as honey bees and bumblebees do.[10]

Centris pallida serve numerous roles for the environment. Like most other bees, they are essential for pollination. Specifically, they pollinate cacti, desert willow, and palo verde.[14] The tunneling ability of these bees aerates the soil, and this allows water from rain to reach plant roots quickly. Their nitrogen rich feces fertilizes the soil.[15] Their stings are mild, so they are not dangerous. The only downside with respect to humans is that their burrowing can leave unsightly mounds. If an area has a large density of burrowing females, then these mounds can be quite noticeable and are difficult to get rid of.[14]

Details: *By default, the Macintosh Centris 610 only supports a single display, but a second one can be supported with the addition of a compatible PDS or NuBus video card. With the standard VRAM, the system is capable of supporting 512x384 at 16-bit color and 640x480, 800x600 and 832x624 at 8-bit color. With 1 MB of VRAM installed, it can support 640x480, 800x600 and 832x624 at 16-bit color and 832x624, 1024x768 and 1152x870 at 8-bit color.
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]
