The green beach insect ( Aiolopus thalassinus ) is a type of short-feeler horror and belongs to the subfamily of the wasteland horror . It is the only species of the genus Aiolopus that occurs in Central Europe .
distribution
There are reports of finds of the green beach insect from southern and southeastern Europe, from Asia to India and Nepal , as well as from the entire African continent. In Germany it reaches the northern limit of its distribution and has so far only been found in the Upper Rhine Valley.
Identifying features
The green wreckage looks more like the grasshopper than the other wasteland terrors, but has no pronotum side keels. Their membership of the Oedipodinae is also recognizable through the structure of the stridulation organs . The body length is 15 to 20 mm in the male and 21 to 30 mm in the female. She has long wings and can fly relatively well. Mostly it has a green basic color, but there are also populations with exclusively brown-black colored animals. The front wings have a conspicuous black and white banding. The rear rails are colored black and white at the base, red or yellow towards the end.
Habitat and way of life
Typical habitat of this species are the banks of small standing water. It is mostly found in open, sparsely vegetated ground, where dry areas border wet areas. Many sites are in sand or clay pits. Sandy or clayey soil seems to be necessary for oviposition. Adult animals can be found from July to October.
Frequency and risk in Germany
In Germany the green beach insect is only represented in the federal states of Rhineland-Palatinate , Baden-Württemberg and Hesse . Original habitats such as floodplains with naturally formed sandbanks are practically nonexistent, however, so the species mainly inhabits secondary biotopes such as sand, gravel or clay pits. Due to its good ability to fly, it is able to colonize newly created biotopes relatively quickly. In the 1990s, as a result of a series of warm years, a clear tendency to spread could be determined. Since the habitats are usually overgrown and overgrown relatively quickly by natural succession or destroyed by recultivation measures, the species is still endangered.
