Leaf Rolling Weevils Attelabidae


There are three species of leaf rolling weevil that you may encounter in the Touraine Loire Valley.

Hazel Leaf Rolling Weevil Apoderus coryli (Fr. L'Apodère du noisetier) makes neat and tidy cylindrical rolls, tucked in at the ends and almost exclusively out of Hazel Corylus avellana leaves. The adult weevil is red with a black head.

Birch Leaf Rolling Weevil Deporaus betulae (Fr. Rhynchite du bouleau) makes rather cone shaped and somewhat untidy 'cigars', narrow at the attached end and widening to the other end, on a variety of tree species -- frequently Hazel, and certainly not exclusively Birch. The adult weevil is black.

Vine Leaf Rolling Weevil Bysticus betulae (Fr. Cigarier). Their rolled leaf is frequently, but not exclusively found on grape vines. They will also use fruit trees such as apples and pears. It uses the entire leaf and produces an untidy cigar shape that tapers at both ends. The adult beetle is metallic green, purple or blue.
