very neatly rolled up hazel leaf forming home for something. Did not look inside as there were only a few of these around and did not want to cause damage to population incase it was rare
No interactions present.
There are three species of weevil that make leaf-rolls on Hazel, but I don't know how to tell them apart. The commonest is Deporaus betulae. The female weevil constructs the leaf-roll and lays an egg in it, and it forms a shelter for the subsequent larva. They are amazing constructions.

This site has plenty of Apoderus coryli weevils but suppose I notice these more easily as the adults are brightly coloured. I had not realised that they make rolls too.
