Rare
Under 5% of wildlife watchers report a Plum Tortrix sighting in Paris on a given day, based on 9 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.
May
In that month about 10% of wildlife watchers report a Plum Tortrix in Paris on a given day, against under 5% in June to April, the lowest months.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Plum Tortrix sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 3 cities where we can rate Plum Tortrix sightings, Paris ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in London (United Kingdom, under 5%) and Vienna (Austria, under 5%).
GBIF citizen-science records
It is estimated from how often the Plum Tortrix is recorded against all the insects logged in Paris (9 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.
