In 3 days ~10% in a week ~20%
Sitochroa palealis, commonly known as the carrot seed moth, is a species of moth in the family Crambidae described by Michael Denis and Ignaz Schiffermüller in 1775. It is found in Europe and in 2002 the first specimen was reported in the United States.
The wingspan is 26–34 mm. The moth flies from June to July depending on the location. The larvae feed on Daucus carota (of which cultivated carrots are a subspecies), Peucedanum oreoselinum, and species from the genera, Heracleum, Foeniculum (which includes cultivated fennel), and Silaum.

GBIF citizen-science records
It is estimated from how often the Carrot Seed Moth is recorded against all the insects logged in Boston (22 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.
