gall

the receptacle is strongly thickened and sclerified and contains several larveae, each one in its own cell..

host plants

Asteraceae, oligophagous

Cirsium arvense, erisithales, palustre, vulgare.

In more southern Europe also Carduus nutans; Galactites tomentosus. A reference to Dittrichia viscosa by Tomasi (2014a) is certainly erroneous.

Euribia stylata
