Centaurea jacea, Belgium, prov. East Flanders, Overboelare, Geraardsbergen, late september @ Bart Uitterhaegen: vertically enlarged receptacle with three opened gall chambers

Urophora jaceana: larva in gall chamber

larva, head downwards, in the gall chamber


one or more larvae (maggots) live, each in its own vertical cell, in the upwards thickened and lignified receptacle; here also the pupation takes place. Because the gall acts as a nutrient sink, the plant’s vitality is reduced.


Asteraceae, narrowly monophagous

Centaurea hanrii subsp. spinabadia, jacea, nigra, phrygia.


Euribia jaceana.


The gall can be found by pinching the old flower heads in autumn.
