Possible
About 20% of wildlife watchers report a Melanostoma mellina sighting in Great Bear Rainforest on a given day, based on 76 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 235 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June
In that month about 30% of wildlife watchers report a Melanostoma mellina in Great Bear Rainforest on a given day, against under 5% in October to April, 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 Melanostoma mellina sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 8 parks where we can rate Melanostoma mellina sightings, Great Bear Rainforest ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Pacific Rim National Park Reserve (Canada, about 20%).
Same family: Syrphidae
The closest relatives of the Melanostoma mellina that you can see in Great Bear Rainforest (family Syrphidae, Hover Flies) are Western Pond Fly (about 20%), Common Drone Fly (about 10%) and Banded Thintail (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Melanostoma mellina is recorded against all the insects logged in Great Bear Rainforest (76 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.
