With luck
About 10% of wildlife watchers report a Melanostoma mellina sighting in Olympic National Park on a given day, based on 27 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 54th most-seen of the 207 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
April and June–October
In those months about 10% of wildlife watchers report a Melanostoma mellina in Olympic National Park on a given day, against under 5% in May and November–March, the lowest months.
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.
7th of 8
Of the 8 parks where we can rate Melanostoma mellina sightings, Olympic National Park ranks 7th at about 10%. The best odds are in Pacific Rim National Park Reserve (Canada, about 20%), 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 Olympic National Park (family Syrphidae, Hover Flies) are Common Drone Fly (about 10%), Western Pond Fly (about 10%) and Black-Margined Flower Fly (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 Olympic National Park (27 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.
