Rare
Under 5% of wildlife watchers report a Dogwood Rivet Gall sighting in Vienna on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 698th most-seen of the 1406 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.
September
In that month about 10% of wildlife watchers report a Dogwood Rivet Gall in Vienna on a given day, against under 5% in October to August, the lowest months.
Only Vienna, in our data
Vienna is the only city on Wallace's Line with enough records to rate Dogwood Rivet Gall sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Dogwood Rivet Gall is recorded against all the insects logged in Vienna (16 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.
