Description of the gall

The yellowish-green gall is found on the underside of a leaf of the host plant. It is pear-shaped, sometimes has two or three lobes and is formed at an angle to the midrib. It can be smooth or hairy. The galls can be found on the leaves of tea-leaved willow (Salix phylicifolia) or its hybrids.[2][3]

Distribution

The gall is found in northern Europe, from Great Britain and Ireland (local in the north of England, Scotland and Ireland), throughout Fennoscandia and in northern Russia (Kanin Peninsula and Yakutia).[1][2]
