The greater lanceolate ( Ruspolia nitidula ) is a species from the subfamily of sword terrors (Conocephalinae).
features
The animals can reach a body length of between 20 and 29 millimeters and are usually completely green; brownish or reddish colored specimens are rarely found. The almost straight laying tube ( ovipositor ) of the females is almost body length and closes approximately with the folded wings towards the rear. The cerci of the males each have two inwardly directed teeth at the tip.
Occurrence
The species is particularly common in southern Europe and colonizes long- grass wet lawns or river banks. In Germany , it was only rediscovered in 1995 on a wet meadow in a low moor on Lake Constance after two individual finds long ago . The species can now be found in southern Upper Swabia, on the southern Upper Rhine and in Rhineland-Palatinate.
The thermophilic species is considered to be widely dispersed and benefits from the current climate change, so it can be assumed that it will change its area significantly in the near future.
Way of life
The adults appear from August and can then be found until October. The male's courtship song includes a very high and loud buzzing. In addition, extremely high -pitched squeaky tones that are close to the ultrasonic range are irregularly built into it.
