Asphondylia pilosa: gall on Cytisus scoparius

larva in the gall


axillary bud changed into a egg-shaped gall with a remarkably long tapering tip; the gall measures up to one cm, and mostly (?) is long, patently hairy. The gall chamber is lined with mycelium. Larva solitary, pupates in the gall.

host plants

Fabaceae, narrowly monophagous

Cytisus scoparius.


Asphondylia pilosa: spatula

spatula (from Kieffer, 1901a)


Asphondylia pilosa: head of pupa

head of the pupa, to show the pair of frontal teeth (from Rübsaamen, 1916b)


Ischnonyx pilosa Ruebsaamen, 1916.


The gall illustrated above is shaped exactly like A. pilosa, but is completely hairlesss. An examination of the larval spatulas, that according to Harris (2002a) show clear differences, effectively did point to pilosa.
