Rabdophaga pulvini (Kieffer, 1891)
galls (from Kieffer)
The reddish larvae cause a swelling of the leaf bases and the adjacent part of the stem (ie, the pulvinus); at best it results in a small rosette consisting of a few disfigured leaves. Often several galls in a row, without shortening of the internodia. Univoltine, hibernation as larva in the gall.
Salicaceae, narrowly monophagous
Salix aurita, caprea, cinerea.
Reference to S, alba, elaeagnos, purpurea are less probable.
larva and pupa
The larva strongly resembles the one of R. clavifex, but the spatula is so weakly chitinised as to be invisible in the living larva. The pupae differ in the shape of the thorax, that in this species overarches the head (Kieffer, 1892a).
Cecidomyia, Dasineura, Helicomyia, Rhabdophaga, pulvini; Rhabdophaga superna (Kieffer, 1897).
In the past often confused with R. rosariella, among others by Buhr (1965a).
