Dichrooscytus gustavi is a type of bug from the family of soft bugs (Miridae). The species isvery closely relatedto Deraeocoris morio . The latter is even considered a synonym by some authors.

features

The bugs are 3.8 to 4.3 millimeters long. Species in the genus Dichrooscytus are strikingly colored and have scarlet and green hemielytras . The head and pronotum are green, the veins of the membranes of the hemielytras are scarlet. Dichrooscytus gustavi is smaller than Dichrooscytus rufipennis and is found less often on Scots pine ( Pinus sylvestris ). The second part of the antennae is somewhat shorter than that of the similar species. It is about the same length as the pronotum is wide.

Occurrence and habitat

The species is distributed in Western Europe from the British Isles, the Netherlands, Luxembourg and France via Germany to Hungary. The exact distribution area has not yet been adequately researched. In Germany, the species is probably widespread, but so far only sporadically proven. It is usually not uncommon. From Austria the species is only documented by old information from the literature, the verification of which is still pending.

Originally dry, warm and open habitats in the mountainous and hilly areas were settled, for example on grazed limestone grasslands. Due to the expansion of their food spectrum, they can also be found in correspondingly new habitats.

Way of life

The bugs live on common juniper ( Juniperus communis ), but are now also found on species originally not native to Central Europe that were used as ornamental plants, including Chinese juniper ( Juniperus chinensis ), sedge tree ( Juniperus sabina ), scaly juniper ( Juniperus squamata ) and also false cypresses ( Chamaecyparis ) and Arborvitae ( Thuja ). The species is usually more common on these plants than on common juniper. The nymphs hatch in May, adult bugs appear from mid-June and can be observed until August. In favorable locations, for example in southwest Germany, there are probably two generations per year, the first of which produces adults from the end of May and the second in September.
