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 →

With luck
About 10% of wildlife watchers report an Italian Tree Cricket sighting in Berlin on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 315th most-seen of the 1065 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report an Italian Tree Cricket in Berlin on a given day, against under 5% in October to June, the lowest months.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Italian Tree Cricket sightings with a recorded time, and about 6 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 8 cities where we can rate Italian Tree Cricket sightings, Berlin ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Vienna (Austria, about 10%) and Budapest (Hungary, about 10%).
GBIF citizen-science records
It is estimated from how often the Italian Tree Cricket is recorded against all the insects logged in Berlin (27 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.
