Possible
About 20% of wildlife watchers report a Spurious Sphinx sighting in Ría Lagartos Biosphere Reserve on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 29th most-seen of the 112 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.
November
In that month about 40% of wildlife watchers report a Spurious Sphinx in Ría Lagartos Biosphere Reserve on a given day, against under 5% in April–May and August–October, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Spurious Sphinx sightings with a recorded time, and about 7 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 Spurious Sphinx sightings, Ría Lagartos Biosphere Reserve has the highest daily chance: about 20%. Next come Cumbres de Monterrey National Park (Mexico, under 5%).
GBIF citizen-science records
It is estimated from how often the Spurious Sphinx is recorded against all the insects logged in Ría Lagartos Biosphere Reserve (17 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.
