Possible
About 30% of wildlife watchers report a Needham's Skimmer sighting in Big Cypress National Preserve on a given day, based on 101 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 262 insects we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.

In that month about 50% of wildlife watchers report a Needham's Skimmer in Big Cypress National Preserve on a given day, against under 5% in December and January, the lowest months. That is one of Big Cypress National Preserve's driest months, with about 65 mm of rain against 260 mm in June.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Needham's Skimmer sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Needham's Skimmer is recorded against all the insects logged in Big Cypress National Preserve (101 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.
