With luck
About 10% of wildlife watchers report a Melanostoma mellina sighting in Portland on a given day, based on 67 verified sightings from GBIF citizen-science data. It is the 100th most-seen of the 507 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.
March
In that month about 20% of wildlife watchers report a Melanostoma mellina in Portland on a given day, against under 5% in May and July–January, the lowest months. That is one of Portland's wettest months, with about 180 mm of rain against 10 mm in July.
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 15 cities where we can rate Melanostoma mellina sightings, Portland ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Brussels (Belgium, about 10%) and Vancouver (Canada, about 10%).
Same family: Syrphidae
The closest relatives of the Melanostoma mellina that you can see in Portland (family Syrphidae, Hover Flies) are Yellow-Haired Sun Fly (about 10%), Narcissus Bulb Fly (about 10%) and Eurasian Drone 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 Portland (67 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.
