In 3 days ~10% in a week ~20%
Isodontia auripes, the brown-legged grass-carrier, is a species of thread-waisted wasp in the family Sphecidae. The wasp will opportunistically use old nests made by Xylocopa virginica or mining bees. Larvae eat for three days and then spend two forming pupae. Oecanthus is a common prey item throughout I. auripes' range. I. auripes lives along the east coast of the United States. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Brown-Legged Grass-Carrying Wasp is recorded against all the insects logged in Boston (18 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.
