Rare
Under 5% of wildlife watchers report a River Jewelwing sighting in Seattle on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 232nd most-seen of the 428 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 River Jewelwing in Seattle on a given day, against under 5% in July to May, the lowest months. That is one of Seattle's driest months, with about 50 mm of rain against 190 mm in November.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most River Jewelwing sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate River Jewelwing sightings, Seattle ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Portland (United States, under 5%).
Same order: Odonata
The closest relatives of the River Jewelwing that you can see in Seattle (order Odonata, Dragonflies and Damselflies) are Eight-Spotted Skimmer (about 20%), Pacific Forktail (about 10%) and Blue Dasher (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the River Jewelwing is recorded against all the insects logged in Seattle (21 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.
