With luck
About 10% of wildlife watchers report an Early Grey sighting in London on a given day, based on 254 verified sightings from GBIF citizen-science data. It is the 210th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
April
In that month about 30% of wildlife watchers report an Early Grey in London on a given day, against under 5% in June to February, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Early Grey sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 5 cities where we can rate Early Grey sightings, London has the highest daily chance: about 10%. Next come Liverpool (United Kingdom, about 10%) and Porto (Portugal, about 10%).
Same family: Noctuidae
The closest relatives of the Early Grey that you can see in London (family Noctuidae, Cutworm Moths and Allies) are Large Yellow Underwing (about 30%), Heart And Dart (about 20%) and Shuttle-Shaped Dart (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Early Grey is recorded against all the insects logged in London (254 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.
