Euura triandrae
Euura triandrae is a sawfly galling Salix triandra. The gall is bean-shaped, starting off green then maturing red. It is smooth and thick-walled, protruding through both the upper and lower leaf surface.
Similar galls are found on Crack Willow, Sallows and White Willow. The host plant must be accurately identified (Almond Willow is a small tree or shrub, much planted for basket withies, and has glabrous narrow glossy leaves, finely serrate, with large stipules)

If a gall, it is essential to say which tree species it was on and provide a photo showing host plant shoots as well as the gall.
The galls are only found on Salix triandra (Almond Willow).
