In 3 days ~10% in a week ~20%
Carmenta ithacae is a root-boring moth of the family Sesiidae. It was described by William Beutenmüller in 1897. It is known from North America, including Florida, Arizona, Illinois, Michigan, Nebraska, New York, Virginia and Wisconsin.
Adults are on wing from late June to July. The larvae feed on various composites like Helenium species, as well as Aster species. C. ithacae has been introduced in Australia as a biological control agent for Parthenium hysterophorus, and is now widespread in central and northern Queensland and recently introduced in the south. Heavily-infested plants often die. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Ithaca Clearwing Moth is recorded against all the insects logged in Minneapolis [Saint Paul] (24 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.
