Italian Tree Cricket

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 of Oecanthus pellucens is yellowish-brown, straw-colored. The body is very elongated and slender. The wings usually protrude out slightly above the abdomen, but can be shorter or longer. The wings of the males are larger than those of females. The antennae are longer than the body. The ovipositor of the female is long and slightly curved. The females are recognizable by the club-shaped end of the ovipositor.

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.
