Mutillidae durable, the exoskeleton is also round, making it more difficult for predators to pierce it with attempted stings or bites. During all the trials that led to the fracture of a velvet ant’s exoskeleton, a total of 4 times, resulted in the death of that velvet ant within 24 hours. Thus aside from protection from predators, the exoskeleton provides a function maintaining moisture control. Male mutillids fly in search of females; after mating, the female enters a host insect nest, typically a ground-nesting bee or wasp burrow, and deposits one egg near each larva or pupa.

Jack jumper ant or not a queen is present in the colony. The ant is a part of the "Myrmecia pilosula" species complex; this ant and other members of the complex are known to have a single pair of chromosomes. Their sting generally only causes a mild local reaction in humans; however, it is one of the few ant species that can be dangerous to humans, along with other ants in the genus "Myrmecia". The ant venom is particularly immunogenic for an insect venom; the venom causes about 90% of Australian ant allergies. In endemic areas, up to 3% of the human population
