Dasymutilla vestita is a species of wasp belonging to the velvet ant Family, the Mutillidae. As in all the family, the females are wingless and look like very large, hairy ants, while males are winged and look like regular wasps. Beyond that, here are features helping with the identification of Dasymutilla vestita:
They are strikingly red and black. From above they look all red, except for black legs, the narrow mid-section, eyes and antennae. From the side they look all red on top except for the mid-section, and all black below. There is a definite, narrow constriction between the hind section, the metasoma, and the middle section, or mesosoma.
Body length is about 9.5 mm long. In Canada Dasymutilla vestita occurs in the provinces of Alberta and Saskatchewan. In the USA it is found throughout the western states as far east as Arkansas and Texas. In Mexico it is seen in the drier parts of the northern, eastern and central states south into Oaxaca, but is absent from the Yucatan Peninsula. In the USA it is regarded as one of the most common and widespread velvet ant species.
In the southwestern USA, Dasymutilla vestita has been recognized... Wikipedia →

Possible
About 20% of wildlife watchers report a Dasymutilla vestita sighting in Zion National Park on a given day, based on 28 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 20th most-seen of the 114 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
May and June
In those months about 30% of wildlife watchers report a Dasymutilla vestita in Zion National Park on a given day, against under 5% in March and October–January, the lowest months. Those are among Zion National Park's driest months, with about 15 mm of rain a month against 75 mm in March.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Dasymutilla vestita sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 parks where we can rate Dasymutilla vestita sightings, Zion National Park has the highest daily chance: about 20%. Next come Grand Canyon National Park (United States, about 10%) and Big Bend National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Dasymutilla vestita is recorded against all the insects logged in Zion National Park (28 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.
