Rare
Under 5% of wildlife watchers report a Gold-Ribbon Argent sighting in Birmingham on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 668th most-seen of the 811 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
In that month about 10% of wildlife watchers report a Gold-Ribbon Argent in Birmingham on a given day, against under 5% in July to May, the lowest months.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Gold-Ribbon Argent sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Birmingham, in our data
Birmingham is the only city on Wallace's Line with enough records to rate Gold-Ribbon Argent sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Gold-Ribbon Argent is recorded against all the insects logged in Birmingham (7 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.
