Description

The beetles can be found from May to July, with the female makes a horseshoe shaped cut and laying an egg in the incision.[3] The gall develops in an internode as a symmetrical swelling, which can be 20 mm long, and contains a yellowish larva or pupa in a single elongate chamber. An exit hole is made in the spring.[4] It is most common on apen (Populus tremula) and also found on black cottonwood (P. trichocarpa), black poplar (P. nigra) and goat willow (Salix caprea).[5] In Britain the gall is commonest on the young twigs of aspen.[4]
