Nabis limbatus (also known as swamp sickle bug ) is a species of bug fromthe sickle bug family (Nabidae).
features
The bugs are 7.2 to 9.2 millimeters long. They have a broad body and very short wings that are almost invariably micropter. These are shorter than in Nabis flavomarginatus and only cover the second and partially the third abdomen segment. Only rarely do individuals with fully developed (macropter) wings appear. The hemielytres have dark vertical stripes. Nabis lineatus is similar but larger and has a narrower connecivium that gives the animals a slimmer appearance. In Nabis lineatus , however, the males are much slimmer than the females, so that this characteristic cannot be used for a reliable determination. The head in front of the compound eyes is about longer than the distance between the eyes. The back of the abdomen wears three dark longitudinal bands. The sides of the abdomen are leaf-like, thin and translucent. They have red spots in some individuals. The thighs ( femora ) of the two front pairs of legs have black lines and dots, those of the hind legs are only dotted.
Occurrence and habitat
The species is common in northern Europe and the northern part of western and central Europe. It occurs in the east across Eastern Europe and Siberia to China and Korea. It was introduced into Canada by humans. The species occurs everywhere in Germany and Austria, but is only common in the north. In the Alps it rises to around 1400 meters above sea level. In the south it is only common in the low mountain ranges.
Like the Nabis lineatus , which is similar in way of life , Nabis limbatus colonizes the tall grass and the herbaceous layer of moist to wet, open to partially shaded habitats with vegetation of sweet and sour grasses . In forests, they are mainly found in clearings, the edges of paths and along lines. Occasionally they are also found in drier places.
Way of life
Nabis limbatus has a non-specific range of prey and hunts both on the ground and in the herb layer. The overwintering takes place as an egg. The nymphs can be observed from mid-May to July, the adults from around the end of June. The females prick their eggs mainly in August in blades of grass or the stems of herbaceous plants. The adults can then be observed up to November at the latest, with the males having largely disappeared by September. The micropter bugs only go through four nymph stages.
