Rare
Under 5% of wildlife watchers report a Chrysotoxum intermedium sighting in Lisbon on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 197th 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.
October to January
In those months about 10% of wildlife watchers report a Chrysotoxum intermedium in Lisbon on a given day, against under 5% in February to September, the lowest months. Those are among Lisbon's wettest months, with about 80 mm of rain a month against almost none in July.

Across all the parks we cover, that three-hour window holds the most Chrysotoxum intermedium sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 cities where we can rate Chrysotoxum intermedium sightings, Lisbon ranks 2nd at under 5%. The best odds are in Barcelona (Spain, about 10%).

GBIF citizen-science records
It is estimated from how often the Chrysotoxum intermedium is recorded against all the insects logged in Lisbon (16 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.
