Guys and Galls

I noted today that a new facebook group has been launched for galls. Which reminded me that I'd photographed a couple whilst out and about lately and then not done anything with them, so here they are .....

Oak Marble Gall

Caused by the asexual generation of the wasp Andricus kollari

Artichoke Gall

Caused by the asexual generation of the wasp Andricus foecundatrix

Bedeguar Gall = Robin's Pincushion Gall
Caused by the wasp Diplolepis rosae

I really ought to make more effort to actually record galls rather than just notice them occasionally!

I also found some dipterous mines recently on Himalayan Balsam, which is handy as there is only one candidate (at present).
