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.

Rare
Under 5% of wildlife watchers report a Great Green Bush-Cricket sighting in Copenhagen on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 249th most-seen of the 476 insects we can rate there. Over three days the chance rises to about 10%, 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 a Great Green Bush-Cricket in Copenhagen on a given day, against under 5% in October to June, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Great Green Bush-Cricket sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
34th of 34
Of the 34 cities where we can rate Great Green Bush-Cricket sightings, Copenhagen ranks 34th at under 5%. The best odds are in Vienna (Austria, about 30%), Budapest (Hungary, about 20%) and Turin (Italy, about 20%).
Same family: Tettigoniidae
The closest relatives of the Great Green Bush-Cricket that you can see in Copenhagen (family Tettigoniidae, Katydids) are Speckled Bush-Cricket (about 20%), Oak Bush-Cricket (about 20%) and Dark Bush-Cricket (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Great Green Bush-Cricket is recorded against all the insects logged in Copenhagen (12 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.
