Possible
About 20% of wildlife watchers report a Melanostoma mellina sighting in Pacific Rim National Park Reserve on a given day, based on 44 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 107 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June and August–September
In those months about 30% of wildlife watchers report a Melanostoma mellina in Pacific Rim National Park Reserve on a given day, against under 5% in November to March, the lowest months. Those are among Pacific Rim National Park Reserve's driest months, with about 110 mm of rain a month against 470 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.
Yes
Of the 8 parks where we can rate Melanostoma mellina sightings, Pacific Rim National Park Reserve has the highest daily chance: about 20%. Next come Great Bear Rainforest (Canada, about 20%) and Gros Morne National Park (Canada, about 10%).
Same family: Syrphidae
The closest relatives of the Melanostoma mellina that you can see in Pacific Rim National Park Reserve (family Syrphidae, Hover Flies) are Common Drone Fly (about 30%), Western Pond Fly (about 20%) and Banded Thintail (about 20%), 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 Pacific Rim National Park Reserve (44 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.
