With luck
About 10% of wildlife watchers report a Tree Snipefly sighting in London on a given day, based on 60 verified sightings from GBIF citizen-science data. It is the 409th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
May–June and August–October
In those months about 10% of wildlife watchers report a Tree Snipefly in London on a given day, against under 5% in July and November–April, the lowest months.
Yes
Of the 2 cities where we can rate Tree Snipefly sightings, London has the highest daily chance: about 10%. Next come Paris (France, under 5%).
GBIF citizen-science records
It is estimated from how often the Tree Snipefly is recorded against all the insects logged in London (60 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.
