Rare
Under 5% of wildlife watchers report an Argyria nivalis sighting in Everglades National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 315th 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 30%, if each day is a fresh chance.
April, June and September
In those months about 10% of wildlife watchers report an Argyria nivalis in Everglades National Park on a given day, against under 5% in May, July–August and October–March, the lowest months. Those are among Everglades National Park's wettest months, with about 180 mm of rain a month against 40 mm in March.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Argyria nivalis sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
3rd of 4
Of the 4 parks where we can rate Argyria nivalis sightings, Everglades National Park ranks 3rd at under 5%. The best odds are in Shenandoah National Park (United States, about 10%) and Acadia National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Argyria nivalis is recorded against all the insects logged in Everglades National Park (8 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.
