british_galls : Message: Re: [british_galls] Unidentified galls

Hello Frazer and welcome to the group

My suggestions for your galls, following Redfern et al, 2002, are;

A = Andricus solitarius (asexual) mature gall

B = Andricus solitarius (asexual) young gall

C = Andricus fecundator? (asexual) young gall (not as sure with this one).

Good luck with the project, feel free to tell u more about it sometime.

Regards

Scotty

Dear all
I am new to this group and am about to start a PhD project involving
Cynipid gall wasps and oak trees. During some preliminary work this
year I have encountered a few galls that I am unsure of, and was
hoping that someone might be able to help. I have posted some images
in a photo album called "Frazers". Any suggestions on what galls they
might be would be greatly appreciated.
Thanks
Frazer

Quite right Karsten I should look more closely - I completely missed the size scale! I have a pic of a young fecundator somewhere, I will dig it out for...
