English: A female of a big grasshopper Decticus verrucivorus is sitting on a log and cleaning its antennae. "The wart-biter (Decticus verrucivorus) is a bush-cricket in the family Tettigoniidae. Its common and scientific names derive from the eighteenth-century Swedish practice of allowing the crickets to nibble at warts to remove them. Adult wart-biters are 31–37 millimetres (1.2–1.5 in), with females being significantly larger than males. They are typically dark green in colour, usually with dark brown blotches on the pronotum and wings (a dark brown morphotype also occurs). The female has a long and slightly upcurved ovipositor. The wart-biter has a song consisting of a rapidly repeated series of short bursts of clicks, sometimes lasting for several minutes. Wart-biters normally move about by walking; they rarely fly, except when frightened. Most can only fly 3 to 4 metres (10 to 13 ft) at a time. The species is omnivorous. Plants eaten include knapweed, nettles, bedstraws; the species also eats insects, including other grasshoppers." (Wikipedia)
