In Bolivia, adults have been reported in March and again from October to December, while adults are on wing year round in Costa Rica. They feed on the nectar of various flowers, including Plumeria rubra in Costa Rica.
The larvae feed on Tecoma and Citharexylum species, Stachytarpheta frantzii, Callicarpa acuminata, Aegiphylla martinicensis, Citharexylum costaricensis, Tabebuia ochracea, Callichlamys latifolia, Cydista heterophylla, Cydista diversifolia, Crescentia alata, Macfadyena unguis-cati, Cordia panamensis, Cordia alliodora and Chionentis panamensis.

With luck
About 10% of wildlife watchers report a Florestan Sphinx sighting in Calakmul Biosphere Reserve on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 46th most-seen of the 75 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
June
In that month about 30% of wildlife watchers report a Florestan Sphinx in Calakmul Biosphere Reserve on a given day, against under 5% in August to May, the lowest months. That is one of Calakmul Biosphere Reserve's wettest months, with about 130 mm of rain against 15 mm in February.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Florestan Sphinx 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 11
Of the 11 parks where we can rate Florestan Sphinx sightings, Calakmul Biosphere Reserve ranks 3rd at about 10%. The best odds are in Brownsberg Nature Park (Suriname, about 40%) and Palo Verde National Park (Costa Rica, about 20%).
GBIF citizen-science records
It is estimated from how often the Florestan Sphinx is recorded against all the insects logged in Calakmul Biosphere Reserve (8 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.
