In 3 days ~30% in a week ~60%
The nettle pouch gall develops in leaf veins, leaf petioles, flower stalks and sometimes the stem of Urtica dioica (and less commonly Urtica urens). This structure is caused by the gall midge Dasineura urticae, sometimes misspelled Dasyneura urticae. Obsolete synonyms are Perrisia urticae and Cecidomyia urticae. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Nettle Pouch Gall Midge is recorded against all the insects logged in Liverpool (59 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.
