Dasymutilla occidentalis (red velvet ant, eastern velvet ant, cow ant or cow killer) [2] [3] [4] is a species of parasitoid wasp that ranges from Connecticut to Kansas in the north and Florida to Texas in the south. Adults are mostly seen in the summer months.
The stridulatory organ that velvet ants possess produces an audible squeaking when the abdomen is contracted. [15] This mechanism is an auditory cue warning predators that are about to attack to stay away. In one experiment, every time a shrew got within 1 meter of a velvet ant, the velvet ant would begin stridulating. [12]

Dasymutilla thetis, also known as the minute thistledown velvet ant, is a species of velvet ant known only from Arizona in North America. [1] It was first described by Charles A. Blake as Sphaerophthalma thetis in 1886. [2] Individuals are about 7 mm long. [1] Females are "clothed entirely with ivory-white setae." [3]: 405
Some caterpillars even bite the female wasps that approach them. Some insects secrete poisonous compounds that kill or drive away the parasitoid. Ants that are in a symbiotic relationship with caterpillars, aphids or scale insects may protect them from attack by wasps. [18] [19] Parasitoid wasps are vulnerable to hyperparasitoid wasps.
