Dasymutilla sackenii, also known as Sacken's velvet ant, is a species of velvet ant, actually a type of wasp. [1] It is found in Oregon, California, Nevada, Baja California, and Baja California Sur. [ 2 ] [ 3 ] : 399 As with most velvet ants, the males have wings and the females are wingless.
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]
The eastern velvet ant is the largest of the velvet ant species in the eastern United States, attaining an approximate length of 0.75 in (1.9 cm). Adults display aposematic coloration , consisting of black overall coloring with an orange-red pattern on the dorsal surface of the thorax and abdomen.
Their range information seems to be somewhat misleading. I live in Middle Tennessee and we certainly do not have sandy soil. As a matter of fact, red clay is the predominant soil type. I just got off the phone with my county extension office and he says they are indeed native here (at least the species I found, the eastern red velvet ant).
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

"An ant ( *Camponotus compressus* ) traverses the edge of a wall during a serene sunset in Southern India. These species, native to tropical regions, are known for their strength and social structures, playing a vital role in the ecosystem by aerating soil and aiding in decomposition."
