In 3 days ~20% in a week ~40%
Cerodontha ircos is a species of fly in the family Agromyzidae. Its larvae form leaf mines on species in the genus Iris. Initially several eggs are deposited inside the leaf, and the larvae form long corridor mines which merge to create the impression of a large blotch. Pupation occurs inside the mine. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Cerodontha ircos is recorded against all the insects logged in Liverpool (21 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.
