Close-Up of a Ephippiger terrestris

Ephippiger terrestris, common name Alpine saddle-backed bush-cricket, is a bush cricket species belonging to the family Tettigoniidae, subfamily Bradyporinae. [1]

Subspecies

Subspecies include: [2]

  • Ephippiger terrestris bormansi Brunner von Wattenwyl, 1882 (in Italy and Switzerland)
  • Ephippiger terrestris caprai Nadig, 1980 (in Italy)
  • Ephippiger terrestris terrestris Yersin, 1854

Distribution

This species is present in Middle and Southwestern Europe ( France, Italy and Switzerland). [3] [4] The subspecies E. terrestris bormansi occurs only in northern Italy and southern Switzerland. [5]

Habitat

This species occurs in warm mountain meadows and pastures, in open rocks and in dwarf shrubs, [5] at an elevation of 1,000–2,000 metres (3,300–6,600 ft) above sea level. [6]

Description

Ephippiger terrestris terrestris. Female

Ephippiger terrestris can reach a body length of about 23–28 mm (0.91–1.10 in) in males, of about 28–32 mm (1.1–1.3 in) in females, while ovipositor can reach about 25–28 mm (0.98–1.10 in). [5]

These bush crickets are usually bluish-green. However, in both sexes the body color is quite variable and often olive-green, beige and sepia-brown color variations occur. A yellowish line runs from the lower edge of the pronotum to the abdomen end. Two bright longitudinal lines run along the back sides. [5]

The back of the head is black. The form of the pronotum is rather smooth and gently concave and resembles a saddle (the Latin name ephippium means 'saddle of a horse'). They have round small atrophied wings, protruding a few millimeters below the pronotum, that are unfit to flight and only used for the emission of sounds ( stridulation). In the females the ovipositor is long and slightly curved upwards. In the male cerci stand out clearly and are cylindrical and relatively long. [5]

Biology

Adults can be found from July to October. [6] The larvae go through about 5 stages. These bush crickets are omnivorous. Both the male and the female can produce sounds, even if the female does so rarely and only in response to other males. [5] [6]
