Tettigonia viridissima, the great green bush-cricket, is a large species of bush-cricket belonging to the subfamily Tettigoniinae. This species can be encountered in most of Europe, in the eastern Palearctic realm, in the Near East, and in North Africa, especially in meadows, grasslands, prairies and occasionally in gardens at an elevation up to 1,800 metres (5,900 ft) above sea level.
The adult males grow up to 28–36 millimetres (1.1–1.4 in) long, while females reach 32–42 millimetres (1.3–1.7 in). This insect is most often completely green (but there are specimens completely yellowish or with yellow legs), excluding a rust-colored band on top of the body. The organ of the stridulation of the males is generally brown.
Tettigonia viridissima is distinguished by its very long and thin antennae, which can sometimes reach up to three times the length of the body, thus differentiating them from grasshoppers, which always carry short antennae. It could be confused with Tettigonia cantans, whose wings are a centimeter shorter than the ovipositor, or Tettigonia caudata, whose hind femurs bear conspicuous black spines.

GBIF citizen-science records
It is estimated from how often the Great Green Bush-Cricket is recorded against all the insects logged in Essen (63 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.
