Rare
Under 5% of wildlife watchers report a Buckthorn Roller sighting in London on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 753rd 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.
June and August
In those months about 10% of wildlife watchers report a Buckthorn Roller in London on a given day, against under 5% in July and September–May, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Buckthorn Roller sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Buckthorn Roller sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Buckthorn Roller is recorded against all the insects logged in London (23 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.
