Rare
Under 5% of wildlife watchers report a Bar-Winged Skimmer sighting in New York City on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 740th most-seen of the 1623 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 Bar-Winged Skimmer in New York City on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Bar-Winged 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.
Only New York City, in our data
New York City is the only city on Wallace's Line with enough records to rate Bar-Winged Skimmer sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Libellula
The closest relatives of the Bar-Winged Skimmer that you can see in New York City (genus Libellula, Chasers and King Skimmers) are Great Blue Skimmer (about 10%) and Twelve-Spotted Skimmer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bar-Winged Skimmer is recorded against all the insects logged in New York City (17 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.
