Monochamus galloprovincialis
In 3 days ~20% in a week ~30%
Monochamus galloprovincialis, the pine sawyer beetle, also referred to as the black pine sawyer beetle, is a species of beetle in the family Cerambycidae. It was described by Olivier in 1795, originally under the genus Cerambyx. It has a wide distribution, occurring naturally throughout Europe and the Caucasus. It has also been introduced into the Canary Islands. It serves as a vector for the parasitic nematode species Bursaphelenchus xylophilus, and also acts as a host to the parasitoid wasp species Dolichomitus tuberculatus.
Adult beetles are strong fliers, and in flight mill experiments were, on average, able to fly 16 km over the lifetime of the beetle. The adult male produces an aggregation pheromone to attract females. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Black Pine Sawyer Beetle is recorded against all the insects logged in Cévennes National Park (9 verified sightings from 2019 to 2026), 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.
