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.

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.

The 18,000 square metres (190,000 sq ft), 12-floor Eton Cyberpod Centris office building targets business process outsourcing companies. Each floor has 2,000 square metres (22,000 sq ft). The building is listed as an approved IT Center by the Philippine Economic Zone Authority, making export-oriented companies located therein eligible for temporary tax holiday, permanent reduced rate of corporate income tax, and other incentives.
Eton Centris was originally being developed by Paramount Land Equities, another Lucio Tan-controlled company. In 2009, Eton Properties purchased the Centris development from Paramount in exchange for 1.6 billion newly issued Eton Properties shares. The shares were issued at ₱2.50 each, a premium of ₱0.17 over the volume-weighted average trading price of the shares in the past three months.

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.
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.
