Rare
Under 5% of wildlife watchers report a Common Groundhopper 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.
August
In that month about 10% of wildlife watchers report a Common Groundhopper in Birmingham on a given day, against under 5% in September to July, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Common Groundhopper sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Birmingham, in our data
Birmingham is the only city on Wallace's Line with enough records to rate Common Groundhopper sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Common Groundhopper 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.
