Anticarsia gemmatalis
In 3 days ~10% in a week ~30%
Anticarsia gemmatalis is a tropical species of caterpillar and moth that migrates north each season. The species can commonly be found in the Gulf states, north as far as Wisconsin. The adults have wings that are grayish brown, crossed with brown or black zigzag lines. The caterpillars are black or green, with narrow lighter stripes on the back and sides. They spit out a brownish substance, spring into the air and wriggle a lot when they are disturbed. The species eats velvet beans, peanut, soybeans, cotton, kudzu, alfalfa, cowpeas, horse beans, snap beans, lima beans, and coffeeweeds. Its common name is velvetbean caterpillar and velvetbean moth.
Egg viability was highest at 25 °C (77 °F) and adaptation to higher temperatures did not occur over a three generation observation. This suggests global warming will reduce A. gemmatalis losses on soybeans in tropical areas that are already at 25 °C (77 °F) but increase predation on soybeans in areas currently below that temperature, thus in fact only shifting the affected area.

Rare
Under 5% of wildlife watchers report a Velvetbean Caterpillar Moth sighting in Everglades National Park on a given day, based on 9 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.
May, August–October and December–January
In those months about 10% of wildlife watchers report a Velvetbean Caterpillar Moth in Everglades National Park on a given day, against under 5% in February–April, June–July and November, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Velvetbean Caterpillar Moth 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 3
Of the 3 parks where we can rate Velvetbean Caterpillar Moth sightings, Everglades National Park ranks 3rd at under 5%. The best odds are in Main Ridge Forest Reserve (Trinidad and Tobago, about 30%) and Merritt Island National Wildlife Refuge (United States, about 10%).
Same family: Erebidae
The closest relatives of the Velvetbean Caterpillar Moth that you can see in Everglades National Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Faithful Beauty (about 20%), Florida Tussock Moth (about 20%) and Polka-Dot Wasp Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Velvetbean Caterpillar Moth is recorded against all the insects logged in Everglades National Park (9 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.
