Australian hornet band marking the abdomen. The insects wings are largely translucent, but tinted orange with black areas at the wing's end. Being a member of the potter wasp subfamily (Eumeninae), "A. ephippium" females build large nests in sheltered positions using mud. The females search for prey (including spiders and caterpillars) around trees and shrubs, before sealing the captured insects inside the nest's cells. The larvae then feed upon these insects, before emerging. Australian hornet The Australian hornet ("Abispa ephippium"), actually a type of potter wasp or "mason wasp", is a vespid insect native to the Australian states and territories of the
Bald-faced hornet the queen's brood. In a sampling of seven "D. maculata nests", 20.9% of males were produced by workers. The percentage of males who were workers’ sons did not correlate with the time during which nests were collected or colony size. Because worker relatedness is so high in "D. maculata", workers are more related to other workers' sons than to the queen's own sons, and therefore worker policing of egg production does not occur. An explanation for the queen's near monopoly on male production is that worker production is costly and therefore reduces total colony reproduction. The cost toward worker production
