With luck
About 10% of wildlife watchers report a Melanostoma mellina sighting in Redwood National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 30th most-seen of the 101 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
February and May–June
In those months about 20% of wildlife watchers report a Melanostoma mellina in Redwood National Park on a given day, against under 5% in April, August–September and November–January, 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.
4th of 8
Of the 8 parks where we can rate Melanostoma mellina sightings, Redwood National Park ranks 4th 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

GBIF citizen-science records
It is estimated from how often the Melanostoma mellina is recorded against all the insects logged in Redwood National Park (14 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.
