Rare
Under 5% of wildlife watchers report an Oedoparena glauca sighting in Seattle on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 306th 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Oedoparena glauca in Seattle on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Oedoparena glauca sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Seattle, in our data
Seattle is the only city on Wallace's Line with enough records to rate Oedoparena glauca sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Diptera
The closest relatives of the Oedoparena glauca that you can see in Seattle (order Diptera, Flies) are Yellow-Haired Sun Fly (about 10%), Eurasian Drone Fly (about 10%) and Narcissus Bulb Fly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Oedoparena glauca is recorded against all the insects logged in Seattle (9 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.
