Rare
Under 5% of wildlife watchers report a Common Red-Legged Robberfly sighting in London on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 688th 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.
May and June
In those months about 10% of wildlife watchers report a Common Red-Legged Robberfly in London on a given day, against under 5% in July to April, the lowest months.
3rd of 4
Of the 4 cities where we can rate Common Red-Legged Robberfly sightings, London ranks 3rd at under 5%. The best odds are in Birmingham (United Kingdom, about 10%) and Copenhagen (Denmark, under 5%).
GBIF citizen-science records
It is estimated from how often the Common Red-Legged Robberfly is recorded against all the insects logged in London (27 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.
