Leptopterna dolabrata is a type of bug from the family of soft bugs (Miridae).
features
The bugs are 7.1 to 9.5 millimeters long. The large species of the genus Leptopterna often have reddish or orange-yellow colored hemielytres . They have sloping pits between the compound eyes and the legs and antennae are hairy with long dark hair. Males and females of Leptopterna dolabrata differ in their appearance ( sexual dimorphism ). Males are always fully winged (macropter), females usually have shortened (brachyptere) hemielytres. The males have a black and yellow to black and orange-red basic color, whereby they become darker with age. The second antennae is much longer than the third and fourth combined. In the females, the second antennae is thinner than the base of the rails ( tibia ) of the front legs. The females are colored green-yellow.
Occurrence and habitat
The species occurs in almost all of Europe to the northern Mediterranean and east across Asia Minor to the Caspian region. It was introduced into North America by humans. It is widespread and common in Central Europe.
Open to partially shaded and, above all, nutrient-rich grass habitats that can be moist to dry are colonized. They can also be found in moors and wet meadows, for example. However, there are also soil types that the species avoids. Sometimes they also live in grain fields, but are not relevant there as pests.
Way of life
The bugs feed on high-growing grasses such as from timothy grass ( Phleum ), foxtail grass ( Alopecurus ), honey grasses ( Holcus ) or ball of grasses ( Dactylis ). They suckle the ears. In the first to third instar , the nymphs also suckle the leaves and stalks of the grass due to the lack of ears. The nymphs hatch from early to mid-May and develop into adult bugs by June. These live until August, females are rarely found in September. They pierce their elongated eggs mainly in July into the cavity of the blades of grass in the lower part of the grass or into the gap between the leaf sheath and the blade.
