With luck
About 10% of wildlife watchers report an Ethmia quadrillella sighting in London on a given day, based on 110 verified sightings from GBIF citizen-science data. It is the 293rd 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.
May to August
In those months about 10% of wildlife watchers report an Ethmia quadrillella in London on a given day, against under 5% in September to April, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Ethmia quadrillella sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Ethmia quadrillella sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ethmia quadrillella is recorded against all the insects logged in London (110 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.
