With luck
About 10% of wildlife watchers report a Common Yellow Conch sighting in London on a given day, based on 69 verified sightings from GBIF citizen-science data. It is the 394th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June to August
In those months about 10% of wildlife watchers report a Common Yellow Conch in London on a given day, against under 5% in September to May, the lowest months.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Common Yellow Conch sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 16 cities where we can rate Common Yellow Conch sightings, London ranks 4th at about 10%, level with the leaders once rounded. The best odds are in Kharkiv (Ukraine, about 10%), Liverpool (United Kingdom, about 10%) and Manchester (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Common Yellow Conch is recorded against all the insects logged in London (69 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.
