A C. pallida female will find a spot for her nest. She will then dig diagonally down about 12 inches (30 cm). At the end of this tunnel, she will dig an 1 inch (2.5 cm) long vertical chamber where the egg will be laid. The chamber will be about 8 inches (20 cm) below the surface. In this chamber, the female will form a brood pot lined with wax. The brood pot will contain nectar and pollen similar to the bee bread in other bees; however, unlike other bees, the bee bread is the consistency of molasses instead of being solid.[7] The egg is laid on top of the bee bread and sealed in with wax, and the tunnel is partially filled with dirt to protect the egg.[8] A female can create several of the burrows during her lifetime.
Larger females are able to better control the size of their offspring. As stated in the Life Cycle section, more bee bread leads to larger offspring. Larger females are able to gather more pollen and nectar in a shorter amount of time when compared to smaller females. This means that during rich conditions, the larger females can have larger offspring with greater fitness, or if conditions are poor, the females can simply choose to have smaller offspring. There is a lower limit to how small offspring can be, and thus, smaller females can’t make this reduction or increase in size in response to the environment. Smaller females are still able to exist since larger females can’t take advantage of having larger offspring when the density of nesting grounds is low.[12] To put it another way, larger male offspring are less effective in low density nesting grounds since they don’t have as many opportunities to use their size to fight off other males; thus, in low density nesting grounds, small and large males have similar fitness which means that the extra bee bread which the larger male received served no purpose. Smaller males actually do better in low density areas because they don’t have to fight with larger males as much, and by extension, expend less energy. This lack of a reason to produce larger offspring reduces the fitness of the larger females since they have to dig larger tunnels to fit in, but still produce the same size offspring as smaller females.[12]
This bee is black and densely covered in a grey pubescence or fur on the dorsal side. The thorax fur has a slightly yellow color. The legs have a mixture of black and reddish fur. The ventral side of the bee is covered in a brownish or dark yellow fur. The wings are fairly transparent except for the black veins that run through them. Males and females are similar in size at about 16–17 millimeters. Males have eyes more yellow in color, and their thorax fur is lighter. Females have eyes more green in color, and their thorax fur is more brown than grey.[3]

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]

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,[1] 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.[1]

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]
