White Velvet Ant Habitat and Other Velvet Ant Species.
In 2015, the USU biologists identified North American velvet ants as one of the world’s largest known Müllerian mimicry complexes.
White Velvet Ant Habitat and Other Species. A phenomenon of quantum mechanics known as superposition can impact timekeeping in high-precision clocks, according to a theoretical study from Dartmouth College, Saint Anselm College….
Males of this species are winged and usually larger than the females.
Well-adapted to the hot, thirsty landscape, the evergreen shrub, also known as greasewood, chaparral and gobernadora, produces tufts of fluffy, white fruit capsules. The Mutillidae are a family of more than 7,000 species of wasps whose wingless females resemble large, hairy ants. A noticeable difference between 2 white velvet ants, the Dasymutilla sackenii and Dasymutilla gloriosa, is in the amount of hair they have; the sackenii has a fuller body of hair whereas the gloriosa´s hair looks a little scraggly and also the sackenii´s legs are a shiny black, but the gloriosa´s legs have white hairs on them. “Their scientific name is Dasymutilla gloriosa and they’re one of my favorites,” says Utah State University biologist Joseph Wilson. Get your Adventure Kit! Thistledown Velvet Ant (Dasymutilla gloriosa), has a cream colored coat with long strands of hair dispersed throughout. Adult Thistle Down Velvet Ants drink nectar. “White coloration can be aposematic, meaning coloring meant to warn or repel predators, but it can also play a role in thermoregulation.”. “It’s logical to assume Thistle-down velvet ants evolved their appearance to hide from predators among fallen creosote fruits,” says Wilson, associate professor in the Department of Biology at USU’s Tooele campus.
USU researchers investigated varied explanations for the insect’s pale coloration. “But the wasps preceded the arrival of the creosote bush to the American Southwest by millions of years. So SUBSCRIBE NOW and join the adventure that brings you closer to the most beloved, bizarre and misunderstood creatures known to man!
“In the animal kingdom, there are relatively few examples of white being an adaptive color outside of arctic environments,” he says. Driving across the arid American Southwest, one views miles upon miles of scrubby creosote bushes. This unusual insect is not really an ant, but a female wasp. The females are quite large (up to 1/2 inch) ,wingless, very hairy and colored bright orange or red with black in between.

Utah State University scientists investigated the idea the wasp’s appearance evolved as camouflage. New Episodes Every Friday and Sunday Subscribe Now! Larvae of the Thistle Down Velvet Ant are parasitic like many species of wasp. The species ranges from Connecticut to Missouri in the north and Florida to Texas in the south. Looking at the velvet ant and creosote fruit side-by-side, it’s easy to imagine the fuzzy wasp’s white coloration evolved as camouflage.

Thistle-down velvet ants are white to us and look like creosote fruit, but we don’t know exactly how they appear to the wasps’ predators.”, Reference: “Thistledown velvet ants in the Desert Mimicry Ring and the evolution of white coloration: Müllerian mimicry, camouflage and thermal ecology” by Joseph S.
