With luck
About 10% of wildlife watchers report a Manduca diffissa sighting in Itatiaia National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 60 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
February
In that month about 40% of wildlife watchers report a Manduca diffissa in Itatiaia National Park on a given day, against under 5% in March–September and November–December, the lowest months. That is one of Itatiaia National Park's wettest months, with about 290 mm of rain against 25 mm in July.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Manduca diffissa sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Itatiaia National Park, in our data
Itatiaia National Park is the only park on Wallace's Line with enough records to rate Manduca diffissa sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Sphingidae

GBIF citizen-science records
It is estimated from how often the Manduca diffissa is recorded against all the insects logged in Itatiaia National Park (5 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.
