Deraeocoris olivaceus is a species of bug from the family of soft bugs (Miridae).
features
The bugs are 8.5 to 10.5 millimeters long. They are relatively large and have a brick-red base color. The females can be confused with Deraeocoris flavilinea , which are smaller and more orange in color. They also lack the long hair on the sides of the pronotum . The nymphs are gray-brown and have striking black bristles.
Occurrence and habitat
The species is distributed in Europe with the exception of the north and south and east to Siberia and across Central Asia to China, Japan and Korea. In Germany, it has been proven up to the northern edge of the low mountain range, and occasionally in the northern German lowlands. It is only found sporadically in Austria, but it is proven in all federal states. Sometimes it is not uncommon locally.
Way of life
The bugs feed predatory and live on older, woody rose plants (Rosaceae) in sunny locations. They are particularly found on hawthorns ( Crataegus ) and sloe ( Prunus spinosa ), otherwise also on fruit trees such as apples ( Malus ), pears ( Pyrus ) and real plums ( Prunus domestica ). They can also be found very rarely on deciduous trees from other plant families, such as oak ( Quercus ), hazelnut ( Corylus ) or ash ( Fraxinus ). Their diet mainly includes aphids and leaf fleas , especially their larvae and eggs from other insects. Older nymphs and adults also suckle on butterfly caterpillars, such as the caterpillars of the spider moths and bud moths (Yponomeutidae). They also seldom suckle on the reproductive organs of the host plants. The overwintering takes place as an egg. The bugs hatch from the end of April; from June, under good conditions even from mid-May, adult bedbugs can appear, but they die quickly after reproduction. In August there are only a few females left.
