Rare
Under 5% of wildlife watchers report a Dark Crimson Underwing sighting in London on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 1219th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Dark Crimson Underwing in London on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Dark Crimson Underwing sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate Dark Crimson Underwing sightings, London ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Munich (Germany, under 5%).
GBIF citizen-science records
It is estimated from how often the Dark Crimson Underwing is recorded against all the insects logged in London (7 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.
