The striped shrimp ( Leptophyes albovittata ) or also white-spotted shrimp is a species from the subfamily of the sickle horror (Phaneropterinae).
features
The animals only reach a body length of 9 to 14 millimeters (males) and 12 to 16 millimeters (females). They have a green basic color with red or dark brown spots all over the body. The upper side of the abdomen of the males is usually brown in color. A white longitudinal line runs between this area and the green colored sides, which arises at the level of the compound eyes and also runs over the sides of the pronotum . This is clearly indented in the shape of a saddle. At its base it covers the approach of the short stub wings. The visible part of the wings is only half as long in the males, in the females a maximum of a third as long as the length of the pronotum. The antennae of both sexes reach about four times the body length. The male has straight, uncurved cerci , each with a small tooth on the inside near the tip. The broad, upwardly curved ovipositor of the females is slightly longer than the pronotum and has fine teeth on the underside of the second half.
Occurrence
The striped shrimp occurs mainly in Eastern Europe . To the west, the border runs along the Würzburg-Nördlingen-Munich line. It has its north-western occurrence in Germany in the nature reserve Besenhorster Sandberge and Elbe Sandwiesen . The animals can be found on dry , bushy grass with favorable temperatures and on the edges of forests. Due to the increasing loss of their habitats, the species is becoming rarer.
Way of life
The phytophagous species feeds mainly on tender and soft-leaved plants such as chickweed , dandelion and flat peas . The male has a very soft courtship song, which as a human being can only be heard about 20 centimeters away. Weak “sb” sounds are sung one after the other. At room temperature, these sequences sound for 5 to 10 seconds. When mating, the male erects his abdomen like in a cat's hump and is mounted by the female. After about one minute, the male releases a spherical spermatophore measuring two millimeters in diameter , which is attached to the female's abdomen. Shortly afterwards the animals separate again. The females lay their eggs in stems of plants or in cracks in bark.
