( Latreille , 1804)

The brown beach insect ( Aiolopus strepens ) is a short-antennae insect from the family of field locusts (Acrididae). It is very widespread in the Mediterranean area and occurs in Central Europe northwards only as far as Ticino , South Tyrol , South Austria and Hungary . Adults of the brown beach insect can be found from late summer to the next spring.

description

The brown beach insect is a medium-sized, relatively slender-winged field grasshopper from the subfamily of the wasteland terrors (Oedipodinae), the males of which are between 18 and 24 mm in length and females between 22 and 32 mm in length.

In contrast to the closely related green beach insect ( A. thalassinus ), it has a relatively compact structure with relatively short hind legs that are at most 3.5 times the height in length. But there are seldom animals that cannot be clearly assigned in this regard. The most important feature for differentiation is therefore the form of the pronotum . This is almost even on the upper side of strepens and not slightly constricted again in the front area in front of the central constriction. In thalassinus it is saddle-shaped and constricted a second time in front. The length of the antennae also provides a distinguishing feature , it is shorter in strepens than the head and pronotum combined, in thalassinus it is just as long.

The basic color is usually a light brown, which is seldom tinged with green or red, but there are also completely green-colored animals, especially females. The pronotum is usually monochrome, rarely with a wide, offset longitudinal stripe on the top, which continues on the top of the head. The rear rails are predominantly red and whitish only on the basal third. The transparent hind wings are often bluish in color at the base, but can also be completely clear here, in the apical part they are darkened brownish.

Up to three subspecies are described, which mainly differ in the color of the hind wings.

  • male

  • female

  • Greenish colored specimen (female)

distribution

The brown beach insect is widespread throughout the Mediterranean and is also found there on the islands (including the Balearic Islands , Malta , Sardinia , Sicily , Cyprus ). The distribution extends in the west to Morocco , to the Canary Islands and Madeira , in the north to Ticino, to South Tyrol and southern Austria, to Hungary and Romania . In North Africa the species can be found southwards to Sudan . Furthermore, the area extends over Egypt to the Middle East and there south to Saudi Arabia . It runs eastwards via Asia Minor to Azerbaijan and further south to Iran and Pakistan .

habitat

This Mediterranean species is more warmth-loving than the green wreckage, which is also widespread in the north, and where both species occur together, it adopts biotopes that are much warmer and dry. In contrast to other Oedipodinae, it prefers sunny, but not too dry, wasteland in the Mediterranean region. It is common almost everywhere there.
