Rare
Under 5% of wildlife watchers report an Oedoparena glauca sighting in Great Bear Rainforest on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 200th most-seen of the 235 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June
In that month about 10% of wildlife watchers report an Oedoparena glauca in Great Bear Rainforest on a given day, against under 5% in July to May, the lowest months. That is one of Great Bear Rainforest's driest months, with about 150 mm of rain against 480 mm in November.
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 Great Bear Rainforest, in our data
Great Bear Rainforest is the only park 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 Great Bear Rainforest (order Diptera, Flies) are Western Pond Fly (about 20%), Melanostoma mellina (about 20%) and Common Drone 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 Great Bear Rainforest (5 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.
