Rare
Under 5% of wildlife watchers report a Vine Sphinx sighting in Cumbres de Monterrey National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 207th most-seen of the 431 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.
May and July–September
In those months about 10% of wildlife watchers report a Vine Sphinx in Cumbres de Monterrey National Park on a given day, against under 5% in June and October–April, the lowest months. Those are among Cumbres de Monterrey National Park's wettest months, with about 140 mm of rain a month against 20 mm in December.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Vine Sphinx sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
4th of 6
Of the 6 parks where we can rate Vine Sphinx sightings, Cumbres de Monterrey National Park ranks 4th at under 5%. The best odds are in Ría Lagartos Biosphere Reserve (Mexico, about 10%), Manu National Park (Peru, about 10%) and Braulio Carrillo National Park (Costa Rica, about 10%).
GBIF citizen-science records
It is estimated from how often the Vine Sphinx is recorded against all the insects logged in Cumbres de Monterrey 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.
