Strong, almost ovoid swelling at the tip of a young shoot, its outside often almost felty hairy; the wall is thin and fleshy. One, proportionally large, gall chamber with up to 22 red larvae. Against end of May fissures form at the bases of leaves that in the mean time have formed on the galls, enabling the larvae to leave and pupate in he soil. The spatula of the larva is yellow; the widened apical part is divided by a sharp incision in two lobes that are longer than wide.
Salix aurita, caprea, cinerea, myrsinifolia.
