larva in the gall
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.
larva
spatula (from Kieffer, 1901a)
pupa
head of the pupa, to show the pair of frontal teeth (from Rübsaamen, 1916b)
synonyms
Ischnonyx pilosa Ruebsaamen, 1916.
notes
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.
