Rare
Under 5% of wildlife watchers report a Philhelius dives sighting in Lisbon on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 324th most-seen of the 441 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Philhelius dives in Lisbon on a given day, so our monthly data shows no clear season.
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.
Among the best
Of the 6 cities where we can rate Philhelius dives sightings, Lisbon ranks 6th at under 5%, level with the leaders once rounded. The best odds are in Barcelona (Spain, under 5%), Kyiv (Ukraine, under 5%) and Vienna (Austria, under 5%).
Same family: Syrphidae
The closest relatives of the Philhelius dives that you can see in Lisbon (family Syrphidae, Hover Flies) are Marmalade Hover Fly (about 10%), Common Drone Fly (about 10%) and Common Globetail (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 Lisbon (7 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.
