Rare
Under 5% of wildlife watchers report a Metallic Harpalus sighting in London on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 547th 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 30%, if each day is a fresh chance.
January and April–May
In those months about 10% of wildlife watchers report a Metallic Harpalus in London on a given day, against under 5% in February–March and June–December, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Metallic Harpalus sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
3rd of 25
Of the 25 cities where we can rate Metallic Harpalus sightings, London ranks 3rd at under 5%. The best odds are in Kyiv (Ukraine, about 10%) and Prague (Czechia, under 5%).
GBIF citizen-science records
It is estimated from how often the Metallic Harpalus is recorded against all the insects logged in London (39 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.
