Asphondylia dorycnii: gall on Dorycnium pentaphyllum

galled pod

gall

Two generations: the first one in the swollen terminal buds of lateral shoots, the second in the galled pods. The first generation hibernates; larva solitary, without a recognisable head, pupation in the gall. Inside of the gall lined with mycelium.
According to Houard and Buhr the gall is densely covered by white unicellular hairs of 15-20 µm thick and 200 µm long. Possibly this is a variable character.

host plants

Fabaceae, monophagous

Dorycnium hirsutum, pentaphyllum & subsp. germanicum + gracile + herbaceum.

pupa

Thy pupa lies freely in the gall, not in a coccoon. Before emergence the pupa works itself half out of the wall of the gall; the pupal skin remains in the opening (Löw, 1881a)

synonyms

Asphondylia dorycnii Löw, 1881.

notes

The two pictures above were taken at the same date (May 28th). Whether, under Spanish conditions, a separation in two generations is justified, seems doubtful.
