Rare
Under 5% of wildlife watchers report a Giant Cranefly sighting in London on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 842nd 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.

In that month about 10% of wildlife watchers report a Giant Cranefly in London on a given day, against under 5% in July to May, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Giant Cranefly sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 6 cities where we can rate Giant Cranefly sightings, London ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Birmingham (United Kingdom, under 5%), Manchester (United Kingdom, under 5%) and Copenhagen (Denmark, under 5%).
GBIF citizen-science records
It is estimated from how often the Giant Cranefly is recorded against all the insects logged in London (16 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.
