The common rose gall wasp ( Diplolepis rosae ) is a representative of the gall wasps (Cynipidae). The 3 to 5 millimeter large wasp develops on roses , forming typical galls at the ends of the shoots. These galls have hair-like growths and are known as rose apples , bedeguare or sleeping apples . The galls got the latter name from folk medicine because they should have a sleep-promoting effect when you put them under the pillow. The galls are hard lignified.
The rose gall has a diameter of up to five centimeters and contains several chambers in which the larvae of the rose gall wasp develop. The reproduction is largely parthenogenic , males are very rare in Central Europe. Pupation occurs in the bile and the adults hatch the following year. A very common parasitoid of Rosengallwespen is Torymus bedeguaris , a species that for Erzwespenfamilie the Torymidae belongs. Numerous other species are parasitoids of the rose gall wasp or equilines ("tenants") in their galls. These are z. B. also relied on other gall wasps of the genus Periclistus as habitat.
