Rare
Under 5% of wildlife watchers report a Hypericum Pigmy sighting in London on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 1153rd 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.
October
In that month about 10% of wildlife watchers report a Hypericum Pigmy in London on a given day, against under 5% in November to September, the lowest months.
Only London, in our data
London is the only city on Wallace's Line with enough records to rate Hypericum Pigmy sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Nepticulidae
The closest relatives of the Hypericum Pigmy that you can see in London (family Nepticulidae, Pygmy Eye-capped Moths) are New Holm-Oak Pigmy (about 10%), Golden Pigmy (about 10%) and Scarce Maple Pigmy (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hypericum Pigmy is recorded against all the insects logged in London (8 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.
