Rare
Under 5% of wildlife watchers report a Common Reed Beetle sighting in Birmingham on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 745th 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.
May
In that month about 10% of wildlife watchers report a Common Reed Beetle in Birmingham on a given day, against under 5% in June to April, the lowest months.
Only Birmingham, in our data
Birmingham is the only city on Wallace's Line with enough records to rate Common Reed Beetle 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 Reed Beetle is recorded against all the insects logged in Birmingham (5 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.
