  • Robins Pincushion

    Whilst on a walk through the Hayling Island nature reserve I found this object on a rose shrub along the trail. It is a gall with relationship between flora and fauna. The object is obviously flora but the fauna aspect is explained below the image.



    Galls are formed by the host plant as a reaction to chemicals being injected by gall wasps. The gall forms protection to the larvae of the wasps until they emerge in the spring as young adult wasps. Each Gall wasp specialises in a particular plant which aids identification of the wasp larvae by identifying the plant on which the Gall is formed. It is fascinating to see this interaction between insects and plants. It is easy to appreciate the advantage given to the wasp by this relationship but I cannot think of any advantage for the plant.

    This Gall is caused by the Diplolepis rosae Gall wasp injecting chemicals in the leaf bud of a rose.

    Thought this may be of interest and encourage you to find more.

    Best wishes

      Thanks for your reply. I have copied the Wikipedia address on this subject, mine was only a brief summary. This makes fascinating reading.
      I hope this answers your query.

            Hi Mark

            Thanks for your reply. To think, if I did not have a camera to record things I see, I might never have taken much notice and it would have been unlikely that I would have carried out research. Cameras are a great tool.

                Some of these wasps have a complex relationship with the host of their eggs. Have a read on Andricus quercuscalicis, which produces the Knopper Gall in native Oaks. They have a two-year breeding cycle. An all female generation lays eggs in the catkins of the non-native Turkey Oak, which hatch into a sexual generation which do their thing and then the sexual females lay eggs in native Sessile or Peduncular oaks. They need both species of tree to breed. How did that evolve

                Good description here

                  A really great find - Thank you, I enjoyed reading the article. Evolution is a wonderful thing. Not only do we have two host plants needed in this wasp's life cycle but we have two types of wasps of the same species in the life cycle. Incredible!
