Diplolepis rosae

Rose apple

The common Rosengallwespe ( Diplolepis rosae ) is a representative of the gall wasps ( Cynipidae ). The to 3 millimeters large wasp develops on roses, forming typical galls on the ends of the shoots. The galls have hair -like outgrowths and are known as rose apple, apple Bedeguare or sleep. The latter name got the gall, because they should induce sleep when you have put them under the pillow. The pockets are lignified hard.

The bile rose has a diameter of up to five centimeters and contains several chambers in which the larvae develop the Rosengallwespe. Procreation is largely parthenogenetic, in Central Europe males are very rare. Pupation occurs in the bile, and the adults emerge in the following year. A very common parasitoid of Rosengallwespen is Torymus bedeguaris, a species that belongs to the Erzwespenfamilie Torymidae. Many other species are parasitoids of Rosengallwespe or inquilines ( " Einmieter " ) in their bile. In this example, are other gall wasps of the genus Periclistus dependent habitat.
