In 3 days ~10% in a week ~20%
Cicada orni, colloquially called the common cicada or ash cicada, is the type species of cicada belonging to the family Cicadidae, subfamily Cicadinae, and the genus Cicada. The genus name comes directly from the Latin cicada 'buzzer', while the species name orni possibly comes from Fraxinus ornus (Manna Ash or South European Flowering Ash), where this cicada often lay its eggs deep in branches.

Rare
Under 5% of wildlife watchers report an Ash Cicada sighting in Paris on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 633rd most-seen of the 916 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.
July
In that month about 10% of wildlife watchers report an Ash Cicada in Paris on a given day, against under 5% in August to June, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Ash Cicada sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
10th of 10
Of the 10 cities where we can rate Ash Cicada sightings, Paris ranks 10th at under 5%. The best odds are in Athens (Greece, about 50%), Rome (Italy, about 20%) and Lisbon (Portugal, about 20%).
Same order: Hemiptera
The closest relatives of the Ash Cicada that you can see in Paris (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are European Firebug (about 40%), Southern Green Stink Bug (about 30%) and Brown Marmorated Stink Bug (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ash Cicada is recorded against all the insects logged in Paris (8 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.
