The small bite insect ( Tessellana veyseli , Syn .: Platycleis veyseli ) is a long- feeler insect from the subfamily of the Tettigoniinae within the superfamily of the deciduous locusts .

features

The body shape of the small bite is similar to other species of the genera Platycleis , Montana and Tessellata such as the brown-spotted bite and the southeastern bite . The species has a straw-colored, light brown to gray-brown basic color with vivid drawing. There is a dark spot above the eye, which is interrupted by a light backward slash. The pronotum lateral lobes are marbled brown and dark gray and have a light and wide whitish border. A black stripe runs across the back of the thigh. The abdomen and back are light beige or yellow-brown, the sides of the abdomen are gray-brown and are separated from the back by a darker stripe. The female has a short, upwardly curved black ovipositor . The forewings, designed as cover wings (Tegmina), are narrow and tapering at the end, they usually do not protrude beyond the tip of the abdomen. More rarely, a fully winged form occurs, which is then very similar to the brown-spotted snatch Tessellana tessellata . It differs from the female by a tooth-like protrusion on the 7th abdominal plate, which protrudes over the edge of the segment, from the male by the cerci, which is toothed just behind the middle (in the brown-spotted bite in the rear third). With a body length of 13 to 17 millimeters, it is one of the smallest species in its genus.

Way of life and distribution

The lesser bite is mostly on the ground. It inhabits rough meadows and dry wasteland with sandy soil. In Central Europe they only exist in Austria in Burgenland and in Lower Austria . In 1997 a specimen of the species was found on a former military training area in Brandenburg . Outside Central Europe, the species occurs in Southeast Europe, West Siberia, West and Central Asia, east to Iran and Kazakhstan. The closed area reaches Lower Austria and Burgenland (Austria), Hungary, Slovakia and South Moravia (Czech Republic) in the west. In the Czech Republic, however, with only two sites left, it may be on the verge of extinction. Adults occur from July to September.

The species is considered harmless (least concern).

Taxonomy and systematics

The species was first described by Toussaint von Charpentier in 1825 under the name Locusta vittata and was later listed as Platycleis vittata for a long time . Charpentier's name was later declared unavailable due to homonymy with Gryllus vittata Thunberg in 1789, so that Koçak coined the replacement name Platycleis veyseli in 1984 . Later, the previous subgenus Tessellana of the genus Platycleis was raised to an independent genus, whereby the name was again changed to Tessellana veyseli .
