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.

With luck
About 10% of wildlife watchers report a Half-Blind Sphinx sighting in Corcovado National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 64th most-seen of the 116 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
February
In that month about 20% of wildlife watchers report a Half-Blind Sphinx in Corcovado National Park on a given day, against under 5% in March to December, the lowest months. That is one of Corcovado National Park's driest months, with about 65 mm of rain against 770 mm in October.
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.
Yes
Of the 2 parks where we can rate Half-Blind Sphinx sightings, Corcovado National Park has the highest daily chance: about 10%. Next come Everglades National Park (United States, under 5%).
Same family: Sphingidae
The closest relatives of the Half-Blind Sphinx that you can see in Corcovado National Park (family Sphingidae, Sphinx Moths) are Tetrio Sphinx (about 10%), Florestan Sphinx (about 10%) and Swift-Winged 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 Corcovado National Park (10 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.
