Hamoir, LIEGE ● Belgium
Description: Females grow to approximately 2 cm and are larger and less active than males that grow to approximately 1.5 cm. Both sexes are flightless. In females the wing cases (covering vestigial wings) extend only a short way down the abdomen while males have longer wing cases extending to almost the tip of the abdomen. They can be variable in colour with green, brownish, purple-red and pink forms recorded, although green forms are most common. Colour forms are genetically determined and some populations can show high frequency of pink grasshoppers.
There are at least five races of the meadow grasshopper described in different regions with the Greek (C. p. tenuis), Iberian (C. p. erythropus) and central European (C. p. parallelus) forms described as separate subspecies. These subspecies are the result of the allopatric separation of Chorthippus parallelus populations into separate southern European refugia during the Pleistocene ice ages.
Biology: Long season with nymphs hatching in April. Adults appear by June and remain abundant through to September, some may survive into November.
The eggs are laid just below the soil and hatch the next spring.
Habitat: It is found amongst long grass, which it eats. It prefers moist vegetation and in southern regions is typically found in river valleys and at altitude (up to approx 2000m), not being found in arid areas.
Distribution: From the Atlantic coast of Europe to the Urals. It is found from Scandinavia in the north to southern Spain and Anatolia in the south.
