With luck
About 10% of wildlife watchers report a Melanostoma mellina sighting in Vancouver on a given day, based on 143 verified sightings from GBIF citizen-science data. It is the 63rd most-seen of the 482 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–May, July and September–October
In those months about 10% of wildlife watchers report a Melanostoma mellina in Vancouver on a given day, against under 5% in June, August and November–February, 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.
Among the best
Of the 15 cities where we can rate Melanostoma mellina sightings, Vancouver ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Brussels (Belgium, about 10%).
Same family: Syrphidae
The closest relatives of the Melanostoma mellina that you can see in Vancouver (family Syrphidae, Hover Flies) are Black-Margined Flower Fly (about 10%), Common Drone 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 Vancouver (143 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.
