Reed-cricket

The adult males grow up to 4.1–4.3 millimetres (0.16–0.17 in) long, while females reach 4.5–5 millimetres (0.18–0.20 in). The overall color is yellowish. Forewings cover entirely the abdomen, hind wings are much longer. The song is a harmonious trill that can be heard from April to the late summer, and is disproportionately strong for a cricket just a few millimeters long: the position of the singing animal is very difficult to locate.

The species was found in several coastal regions of Italy, mostly on the Thyrrhenian coast, as well as in Sardinia and Sicily. N. averni was also found in Corsica, in the Balearic Islands, in the Canary Islands and in Turkey. The taxonomic status of this species is still controversial. Even though currently its range is considered to include southern Europe and Turkey, it may be synonymous with Natula longipennis, in which case its range would include Africa and Asia. Furthermore, it could be a species complex, consisting of more species even in southern Europe.
