Rare
Under 5% of wildlife watchers report a Chocolate-Tip sighting in London on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 931st 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
In that month about 10% of wildlife watchers report a Chocolate-Tip in London on a given day, against under 5% in June to April, the lowest months.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Chocolate-Tip 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 3 cities where we can rate Chocolate-Tip sightings, London ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Porto (Portugal, under 5%) and Liverpool (United Kingdom, under 5%).
Same family: Notodontidae
The closest relatives of the Chocolate-Tip that you can see in London (family Notodontidae, Prominent Moths) are Buff-Tip (about 10%), Oak Processionary (about 10%) and Pale Prominent (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chocolate-Tip is recorded against all the insects logged in London (13 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.
