Possible
About 20% of wildlife watchers report a Darceta Sphinx sighting in Tambopata National Reserve on a given day, based on 25 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 141 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April and July
In those months about 30% of wildlife watchers report a Darceta Sphinx in Tambopata National Reserve on a given day, against under 5% in March, October and December–January, the lowest months. Those are among Tambopata National Reserve's driest months, with about 120 mm of rain a month against 420 mm in February.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Darceta 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 6 parks where we can rate Darceta Sphinx sightings, Tambopata National Reserve has the highest daily chance: about 20%. Next come Tapantí-Macizo de la Muerte National Park (Costa Rica, about 10%) and Arenal Volcano National Park (Costa Rica, about 10%).
GBIF citizen-science records
It is estimated from how often the Darceta Sphinx is recorded against all the insects logged in Tambopata National Reserve (25 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.
