''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.

''Tettigonia viridissima'' is carnivorous and arboreal. Its diet is mostly composed of

, caterpillars and larvae. Unlike grasshoppers, it is essentially active in day and night, as testified by its endless crepuscular and nocturnal singing. The species can bite painfully but is not particularly aggressive. It is best to avoid holding the insect in the fist, as that almost guarantees a bite. They can fly, but they tend to avoid flying where possible. Most often they move "on foot" or jumps, which allow them to travel about in bushes and trees.
