Rare
Under 5% of wildlife watchers report a Seagrape Spanworm Moth sighting in Everglades National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 396th 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 and November–December
In those months about 10% of wildlife watchers report a Seagrape Spanworm Moth in Everglades National Park on a given day, against under 5% in January–March and May–October, the lowest months. Those are among Everglades National Park's driest months, with about 60 mm of rain a month against 240 mm in June.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Seagrape Spanworm Moth sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Everglades National Park, in our data
Everglades National Park is the only park on Wallace's Line with enough records to rate Seagrape Spanworm Moth sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Geometridae

GBIF citizen-science records
It is estimated from how often the Seagrape Spanworm Moth is recorded against all the insects logged in Everglades National Park (6 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.
