Oecanthus pellucens, common name European tree cricket, is a species of tree crickets belonging to the family Oecanthidae, subfamily Oecanthinae. This species is present in most of Europe, especially in the countries around the Mediterranean with a focus on Southern Europe. The northern boundary runs through northern France, Belgium, southern Germany, the Czech Republic and southern Poland. The first, apparently viable, British colony was discovered near Dungeness in Kent in 2015. In southern Europe there is also the closely related and very similar species Oecanthus dulcisonans. It is also present in the eastern Palearctic realm, in the Near East, and in North Africa.
The typical habitat of Oecanthus pellucens are sunny meadows with high vegetation and dry warm and nutrient-poor areas such as grasslands, sand dunes and brownfield lands. The adult males grow up to 10–13 millimetres (0.39–0.51 in) long, the female is slightly larger than the male, about 11–14 millimetres (0.43–0.55 in) long. The colouration... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Italian Tree Cricket is recorded against all the insects logged in Białowieża National Park (7 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.
