Argyrotaenia velutinana
In 3 days ~10% in a week ~20%
Argyrotaenia velutinana, the red-banded leafroller moth, is a species of moth of the family Tortricidae. It is found in the eastern United States and south-eastern Canada, from Quebec and Ontario to Florida, west to Texas and at least Iowa. It has also been reported from British Columbia.
The wingspan is 13–20 millimetres (1⁄2–3⁄4 in). Neonatal larvae are not thought to naturally commit egg cannibalism. However Rock 1968 was able to induce it in laboratory conditions. They go on to feed on various plants, including the leaves and fruit of apple and other fruit trees, as well as spruce and various vegetables. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Red-Banded Leafroller Moth is recorded against all the insects logged in Philadelphia (5 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.
