Phytocoris dimidiatus is a species of bug from the family of soft bugs (Miridae).

features

The bugs are 5.5 to 7.2 millimeters long. The species of the genus Phytocoris can be recognized by their long thighs ( femora ) of the hind legs and the long first antennae . Only Miridius quadrivirgatus also has these characteristics. Phytocoris dimidiatus can be recognized by the not sharply demarcated black color on the pronotum and the strongly dark spotted upper side of the body. The pale bandages on the rails ( tibia ) of the middle legs are narrower or the same width as the dark bandages. The species is very similar to Phytocoris reuteri and can only be reliably differentiated from it through a genital morphological examination. Both the males and the females are fully winged (macropter).

Occurrence and habitat

The species is common in Europe with the exception of the far north and the eastern Mediterranean and east to Central Asia. It was introduced into North America by humans. It is widespread in Germany and Austria and also occurs in the low mountain ranges. It is not often, but can still be found regularly.

Way of life

The bugs live on deciduous trees. They are found on fruit trees such as apples ( Malus ), pears ( Pyrus ) and plums ( Prunus domestica ), preferably on older trees with lichen growth. They are less common on oak ( Quercus ), linden ( Tilia ), beech ( Fagus ), ash ( Fraxinus ) or willow ( Salix ). During the day, the animals sit on the trunk or on thick branches between lichens and crevices in the bark. They feed on zoophytophagus. The males in particular are attracted to artificial light sources at night. The nymphs appear from April, the adults from mid-June, rarely also from the end of May and can be observed until November. Therefore, it is believed that the species occurs in two generations per year.
