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] As with most velvet ants, the males have wings and the females are wingless. The females of this species have cream-colored fuzz (setae) on their backs and black fuzz on their ventral side and legs. D. sackenii is most commonly observed May through October; observations December through February are very rare.
D. sackenii superficially resembles Dasymutilla albiceris and they also have a similar geographic distribution.[3]
The specific name honors 19th-century German diplomat and entomologist Carl Robert Osten-Sacken.
