Rare
Under 5% of wildlife watchers report a Nebula Brown 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.
April–June and September
In those months about 10% of wildlife watchers report a Nebula Brown in Everglades National Park on a given day, against under 5% in July–August and October–March, 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 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Nebula Brown sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
2nd of 2
Of the 2 parks where we can rate Nebula Brown sightings, Everglades National Park ranks 2nd at under 5%. The best odds are in Big Cypress National Preserve (United States, about 10%).
Same family: Noctuidae
The closest relatives of the Nebula Brown that you can see in Everglades National Park (family Noctuidae, Cutworm Moths and Allies) are Spanish Moth (about 20%), Pearly Wood-Nymph (about 10%) and Florida Fern Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Nebula Brown 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.
