Rare
Under 5% of wildlife watchers report a Buttoned Snout 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Buttoned Snout in London on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Buttoned Snout 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.
12th of 13
Of the 13 cities where we can rate Buttoned Snout sightings, London ranks 12th at under 5%. The best odds are in Kyiv (Ukraine, about 10%), Berlin (Germany, about 10%) and Almaty (Kazakhstan, about 10%).
GBIF citizen-science records
It is estimated from how often the Buttoned Snout 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.
