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.

Ant is used to trap their insect prey. Lemon ants make devil's gardens by killing surrounding plants with their stings and leaving a pure patch of lemon ant trees, ("Duroia hirsuta"). This modification of the forest provides the ants with more nesting sites inside the stems of the "Duroia" trees. Although some ants obtain nectar from flowers, pollination by ants is somewhat rare, one example being of the pollination of the orchid "Leporella fimbriata" which induces male "Myrmecia urens" to pseudocopulate with the flowers, transferring pollen in the process. One theory that has been proposed for the rarity of pollination is
