In 3 days ~30% in a week ~50%
The red-banded hairstreak (Calycopis cecrops) is a butterfly native to the southeastern United States. It feeds on fallen leaves of sumac species and other trees. It is 0.9–1.25 inches (23–32 mm) in size. It lives near coastal areas.
Its genome was sequenced in 2016. It has a false "head" that helps it avoid predators. In a 2012 experiment, C. cecrops was exposed to a jumping spider, Phidippus pulcherrimus, which researchers found to be a "very efficient strategy in deflecting attacks." Wikipedia →

GBIF citizen-science records
It is estimated from how often the Red-Banded Hairstreak is recorded against all the insects logged in Washington (495 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.
