Rare
Under 5% of wildlife watchers report a Sphex dorsalis sighting in Everglades National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 439th most-seen of the 496 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.
June and August–September
In those months about 10% of wildlife watchers report a Sphex dorsalis in Everglades National Park on a given day, against under 5% in July and October–May, the lowest months. Those are among Everglades National Park's wettest months, with about 220 mm of rain a month against 40 mm in March.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Sphex dorsalis sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Everglades National Park, in our data
Everglades National Park is the only park on Wallace's Line with enough records to rate Sphex dorsalis sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Sphex
The closest relatives of the Sphex dorsalis that you can see in Everglades National Park (genus Sphex) are Jamaican Digger Wasp (about 10%) and Great Golden Digger Wasp (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sphex dorsalis is recorded against all the insects logged in Everglades National Park (6 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.
