Rare
Under 5% of wildlife watchers report a Chrysopilus basilaris 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.
February and May
In those months about 10% of wildlife watchers report a Chrysopilus basilaris in Everglades National Park on a given day, against under 5% in March–April and June–January, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Chrysopilus basilaris sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Everglades National Park, in our data
Everglades National Park is the only park on Wallace's Line with enough records to rate Chrysopilus basilaris sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Chrysopilus basilaris 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.
