In 3 days ~10% in a week ~30%
Euxoa ochrogaster, the red-backed cutworm, is a moth of the family Noctuidae. It is found from Iceland and northern Europe, through the Baltic to the Amur region. In North America, it is found from Alaska to Newfoundland and Labrador, south into the northern part of the United States, south in Rocky Mountains to Arizona and New Mexico.
Adults are on wing from the end of July to beginning of September. The larvae feed on a variety of broad leaf plants and grasses, including Plantago species. The species is economically important on Helianthus annuus in North America.
The moths can be affected by a fungus Tarichium megaspermum (from order Entomophthorales), in British Columbia, Canada. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Red-Backed Cutworm Moth is recorded against all the insects logged in Edmonton (19 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.
