I never knew that! Thanks alot for the info. Do other species have this too?The species is undoubtedly Dasymutilla occidentalis.
The "hissing" is really called stridulation, which takes place on the abdomen. Velvet ants have a stridulatory file on their third abdominal tergite. The scraper is on the underside of the second tergite. So when the scraper is rubbed against the file, it creates the distinctive sound. The sound is associated with mating and defense, but its purpose is not 100% known (it may be associated with other things as well, mutillid biology still needs a lot of work).
