Rare
Under 5% of wildlife watchers report a Double-Toothed Prominent sighting in Austin on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 1316th most-seen of the 1624 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Double-Toothed Prominent in Austin on a given day, so our monthly data shows no clear season.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Double-Toothed Prominent 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 Austin, in our data
Austin is the only city on Wallace's Line with enough records to rate Double-Toothed Prominent sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Double-Toothed Prominent is recorded against all the insects logged in Austin (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.
