Rare
Under 5% of wildlife watchers report a Spangled Skimmer sighting in Washington on a given day, based on 31 verified sightings from GBIF citizen-science data. It is the 627th most-seen of the 1807 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
In that month about 10% of wildlife watchers report a Spangled Skimmer in Washington on a given day, against under 5% in July to May, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Spangled Skimmer sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Washington, in our data
Washington is the only city on Wallace's Line with enough records to rate Spangled Skimmer sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Libellula
The closest relatives of the Spangled Skimmer that you can see in Washington (genus Libellula, Chasers and King Skimmers) are Slaty Skimmer (about 10%), Great Blue Skimmer (about 10%) and Needham's Skimmer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Spangled Skimmer is recorded against all the insects logged in Washington (31 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.
