Under 5% of wildlife watchers report a Mahogany Dun sighting in Dallas on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 1307th most-seen of the 1412 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Mahogany Dun in Dallas on a given day, so our monthly data shows no clear season.
Only Dallas, in our data
Dallas is the only city on Wallace's Line with enough records to rate Mahogany Dun sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Mahogany Dun is recorded against all the insects logged in Dallas (6 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.
