M. flavitarsis feed on arthropods, nectar, and animal carcasses and are often prey to birds, ants, and praying mantis.
Henri Louis Frédéric de Saussure, a Swiss mineralogist and entomologist, classified M. flavitarsis in 1854. The genus Mischocyttarus is the only genus in the tribe Mischocyttarini and is the second largest genus of social wasps. Mischocyttarus species are recognizable by the internal and external...

GBIF citizen-science records
It is estimated from how often the Western Paper Wasp is recorded against all the insects logged in Salt Lake City (10 verified sightings), 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.
