Bald-faced hornet viable brood in the comb fragment. The physical nature of cues mediating natal comb recognition is unknown, though some researchers propose distinct cuticular hydrocarbon profiles allow wasps to recognize nest mates. "D. maculata" is characterized by low paternity, worker reproduction and queen-worker conflict. Divergent genetic interests between workers and their queen cause intra-nest struggle for control, which disrupts social organization. Because of haplodiploidy, workers are unable to mate. However, their unfertilized eggs become males. Workers and their queens are most related to their own sons. Natural selection will therefore favor those workers who produce their own sons rather than rearing
Asian hornet find a bee colony or an apiary, they tend to settle down and specialise in honeybees as their prey. A hornet occupies a position above a beehive as its hunting territory. It flies about within an area of about half a square metre, scanning the direction from which foraging bees return to the hive. Each hornet vigorously defends its hunting territory, chasing off any rivals. However, as soon as it catches a bee it flies off and another hornet replaces it, usually within a few seconds. The circadian activities of the two species of honeybees are similar, and the hunting
