Rare
Under 5% of wildlife watchers report a Philhelius dives sighting in Barcelona on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 229th most-seen of the 381 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March–June and October
In those months about 10% of wildlife watchers report a Philhelius dives in Barcelona on a given day, against under 5% in July–September and November–February, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Philhelius dives sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 6 cities where we can rate Philhelius dives sightings, Barcelona has the highest daily chance: under 5%. Next come Kyiv (Ukraine, under 5%) and Vienna (Austria, under 5%).
Same family: Syrphidae
The closest relatives of the Philhelius dives that you can see in Barcelona (family Syrphidae, Hover Flies) are Marmalade Hover Fly (about 20%), Common Drone Fly (about 10%) and Stripe-Eyed Lagoon Fly (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Philhelius dives is recorded against all the insects logged in Barcelona (10 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.
