Under 5% of wildlife watchers report a Longitarsus dorsalis sighting in London on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 931st most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January–March and November
In those months about 10% of wildlife watchers report a Longitarsus dorsalis in London on a given day, against under 5% in April–October and December, the lowest months.
Only London, in our data

Same family: Chrysomelidae

GBIF citizen-science records
It is estimated from how often the Longitarsus dorsalis is recorded against all the insects logged in London (15 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.
