GALLS

WILLOW/SALLOW

Camellia gall, aka Rosette Gall, is an abnormality caused by midge Rabdophaga rosaria. The galls consist of 30 or more short leaves with each containing a single pinkish larva in the middle which overwinters inside the gall on the tree. Mature galls turn brown.

Pustule Galls on Willow leaves are caused by the mite Aculus tetanothrix, especially on White Willow. The green or reddish galls appear of the upper surface of the leaf. There is a slit on the underside which is hairy inside.

Leaf Galls on Sallow and Willow are caused by midge Iteomyia major. They appear on both upper and lower sides of the leaf.

Hairy Pea Galls on the underside of Sallow leaves are caused by Willow Gall Sawfly Eupontania pedunculi. A tiny circular shiny yellowish patch appears on the upper leaf surface which can be flush or very slightly raised.
