Rare
Under 5% of wildlife watchers report a Tawny Pennant sighting in Everglades National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 439th most-seen of the 496 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–June, September and November
In those months about 10% of wildlife watchers report a Tawny Pennant in Everglades National Park on a given day, against under 5% in July–August, October and December–April, the lowest months. Those are among Everglades National Park's wettest months, with about 170 mm of rain a month against 40 mm in March.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Tawny Pennant sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
6th of 6
Of the 6 parks where we can rate Tawny Pennant sightings, Everglades National Park ranks 6th at under 5%. The best odds are in Lago de Yojoa (Honduras, about 10%), Cerro Azul Meámbar National Park (Honduras, about 10%) and Soberanía National Park (Panama, about 10%).
GBIF citizen-science records
It is estimated from how often the Tawny Pennant is recorded against all the insects logged in Everglades National Park (5 verified sightings from 2019 to 2026), 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.
