Rare
Under 5% of wildlife watchers report a Vine Sphinx sighting in Dallas on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 913th most-seen of the 1412 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Vine Sphinx in Dallas on a given day, so our monthly data shows no clear season.
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.
12th of 12
Of the 12 cities where we can rate Vine Sphinx sightings, Dallas ranks 12th at under 5%. The best odds are in Santo Domingo (Dominican Republic, about 20%), San Antonio (United States, about 10%) and Manaus (Brazil, about 10%).
GBIF citizen-science records
It is estimated from how often the Vine Sphinx is recorded against all the insects logged in Dallas (11 verified sightings), 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.
