Albuna fraxini, the Virginia creeper clearwing, is a moth of the family Sesiidae. It is known from the northern United States and southern Canada. The wingspan is about 18 mm. Adults are on wing from June to August. Adults generally only live for a week.
Females emit pheromones to attract mates soon after emerging from pupae. The larvae feed on Virginia creeper, white, red, green, and European ash, and sometimes mountain-ash. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Virginia Creeper Clearwing is recorded against all the insects logged in Chicago (12 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.
