Rare
Under 5% of wildlife watchers report a Curve-Lined Cydosia 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.
July and October–November
In those months about 10% of wildlife watchers report a Curve-Lined Cydosia in Everglades National Park on a given day, against under 5% in August–September and December–June, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Curve-Lined Cydosia 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 Curve-Lined Cydosia sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Noctuidae
The closest relatives of the Curve-Lined Cydosia 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 Curve-Lined Cydosia 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.
