Galls are fascinating for me and I see quite a lot of them on Acacia trees. They never disappoint and usually have something interesting to see on them – even if it’s only a colony of Technomyrmex ants using a dead gall as a camp site. Most times though I can find beautiful little wasps like this Neanastatus sp. which is seen here laying some eggs. The first image shows the entire gall which has already had something hatch from it (see the holes) and you can see our wasp on the left section which seems to be new gall tissue. It’s most likely this wasp is parasitising the organism that created the gall as Neanastatus wasps are known to parasitise gall inducing organisms.
