I'm not sure if this fly is associated with the gall it is resting on. Seen in September, England. Any ideas?

again... this is a parasitoid wasp. Hymenoptera. |

Perhaps Eurytomidae? I thought these liked to parasitise on gall insects.

I'd go with Ptermomalidae but I'm no expert  There are plemty of pteromalids associated with gall communities.

Indeed, a parasitic wasp. Two most common options are Entedon sp. (Eulophidae) or Pteromalus (Habrocytus) sp. (Pteromalidae). Both are of similar size and shape, differing in details (indistinct here); if that was a fruit fly gall on a thistle, Pteromalus is more reliable; in the case of a weevil gall, it could be an Entodon. Also, Entodons often hav e"white socks"
