Eremnophila aureonotata, also known as the gold-marked thread-waisted wasp, is a species in the family Sphecidae ("thread-waisted wasps") found in North and South America. Their coloration is black with 2 pairs gold patches of setae one on the side of their thorax and one on the propodeum. Adults drink nectar while larvae feed on caterpillars. Females dig vertical burrows in sand or hard-packed loam to lay eggs in and provision the nests with a single caterpillar. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Gold-Marked Thread-Waisted Wasp is recorded against all the insects logged in Chicago (31 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.
