Dasymutilla occidentalis (red velvet ant, eastern velvet ant, cow ant or cow killer) 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 eastern velvet ant is the largest of the velvet ant species in the eastern United States, attaining an approximate length of 1.9 cm (0.75 in). Adults display aposematic coloration, consisting of black overall coloring with an orange-red pattern on the dorsal surface of the thorax and abdomen.
Commonly mistaken for an ant because of its appearance and its common name, it is a parasitoid wasp species in which the females are wingless, as is true for all females of Mutillidae. It can be recognized by its distinctive coloring, black with bright red on the upper side of the head, thorax, and abdomen. They are quick-moving and often take a defensive posture when threatened. Unlike the females, males have dark, translucent wings and do not possess a stinger.
Dasymutilla occidentalis plays an ecological role as parasites and prey. Dasymutilla species have multiple defensive strategies... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Common Eastern Velvet Ant is recorded against all the insects logged in Everglades National Park (30 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
