a couple of years ago and found out they are also called Bedeguar galls. They are formed on the wild rose by larvae of the gall-wasp Diplolepis rosae, it is not the product of a single larva but a group of larvae each residing in its own chamber in the gall. The wasps over winter in the gall emerging as adults in spring, they reproduce without males ~ parthenogenetically.

these galls can contain many other species, some harmless squatters, some parasitising the wasp larvae.
Thats fascinating thank you very much for the additional information. Regards Tracy
