Himacerus major is a species of bug fromthe sickle bug family (Nabidae).

features

The bugs become 7.5 to 9.1 millimeters long. The adults always have fully developed (macroptere) wings. Based on this and the pale colored connexivium, they have a stronger resemblance to members of the genus Nabis than to the other species of their genus. You can determine the type based on the thighs ( femora ) on the hind legs. These have a broad black band at their tip, but have a number of dark spots underneath, but the Himacerus boops , which have such a band, are missing.

Occurrence and habitat

The species is distributed from the south of Scandinavia and the south of the British Isles across Western Europe to the western Mediterranean and across Central and Eastern Europe to the Caucasus. It is also common in North America. In Germany it is mostly common in the north and west, in the south-east it becomes rarer and can also be absent. In Austria it is only found in the east, in Lower Austria, Vienna and Burgenland and is rare.

Many different habitats are populated with grass cover, regardless of the degree of humidity. The species occurs on very dry dune habitats and grasslands, as well as on moist banks of water bodies without woody vegetation and also on salt patches inland. The species occurs in very large numbers near the coast of the North Baltic Sea. The species is absent in forests.

Way of life

The young nymphs of Himacerus major live mostly on the ground. Older nymphs and adults can sometimes be found in higher parts of vegetation such as shrubs during the day and more often at night. During the day they usually hide in the litter or in grass clusters or something similar. It is not known whether the species has a specific range of prey. They have been observed sucking on cicadas. The overwintering takes place as an egg. The nymphs appear from May and can be observed until autumn. The adult bugs appear from July, rarely from the end of June, and are mainly active in August and September. The eggs can also be laid in November. The females pierce their eggs in blades of grass.
