In 3 days ~10% in a week ~30%
Perigonia lusca, the half-blind sphinx or coffee sphinx, is a moth of the family Sphingidae. It was first described by Johan Christian Fabricius in 1777. It is found from the northern tip of South America, through most of Central America, and northward to Florida in the United States.
The wingspan is 55–65 mm. There are several generations per year in southern Florida. On the Galápagos Islands, adults are on wing in April and July. In the tropics, adults are probably on wing year round. The larvae have been recorded feeding on Guettarda macrosperma, Guettarda scabra, Coffea species (including Coffea arabica), Ilex krugiana, Ilex paraguariensis, Genipa americana, Rondeletia, Gonzalagunia species (including Gonzalagunia spicata) and Cinchona succirubra.

Rare
Under 5% of wildlife watchers report a Half-Blind Sphinx sighting in Everglades National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 292nd 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 December–January
In those months about 10% of wildlife watchers report a Half-Blind Sphinx in Everglades National Park on a given day, against under 5% in February–March and May–November, 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 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Half-Blind Sphinx sightings with a recorded time, and about 9 in 10 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 Half-Blind Sphinx sightings, Everglades National Park ranks 2nd at under 5%. The best odds are in Corcovado National Park (Costa Rica, about 10%).
Same family: Sphingidae
The closest relatives of the Half-Blind Sphinx that you can see in Everglades National Park (family Sphingidae, Sphinx Moths) are Tersa Sphinx (about 10%), Giant Sphinx (about 10%) and Grote's Sphinx (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Half-Blind Sphinx is recorded against all the insects logged in Everglades National Park (12 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.
