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 cocoon. 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.

parasitoids, predators

Eupelmus barai; Sigmophora italica.

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.
