Bedeguar Gall 3 certainly has been a mega producer with the 117 D. rosae and 10 O. mediator meaning that there must have been 127 D. rosae initially from the one gall. Although I say the one gall I can not help but wonder if it is actually a couple of galls that have merged together. This I hope to find out by cutting the gall open but I will wait till I know that it is empty. although there has been no activity for a few days T. bedeguaris can emerge upto a month after the initial exits so I will wait for a bit longer.
I have to admit sympathies to the local Rosa canina population with over 200 females released locally at several different sites. I have release the hyperparasites as well but they have all been released at home to help new colonies of D. rosae to form free of paratisation.

The galls collected where all galls that would have been destroyed by hedgecutting and where the hedges were not cut the galls were left in place.
