With luck
About 10% of wildlife watchers report a Migrant Hover Fly sighting in Camargue on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 25th most-seen of the 75 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.
January–February, May–June and October
In those months about 20% of wildlife watchers report a Migrant Hover Fly in Camargue on a given day, against under 5% in March, July–September and November–December, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Migrant Hover Fly 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 10 parks where we can rate Migrant Hover Fly sightings, Camargue ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Sierra Nevada National Park (Spain, about 10%).
Same family: Syrphidae
The closest relatives of the Migrant Hover Fly that you can see in Camargue (family Syrphidae, Hover Flies) are Big-Headed Lagoon Fly (about 10%), Common Lagoon Fly (about 10%) and Marmalade Hover Fly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Migrant Hover Fly is recorded against all the insects logged in Camargue (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.
