gall
There are two annual generations. According to, among others, Buhr and Skuhravá, Skuhravý & Jörgensen pupation takes place in the soil, but, as the pictures above show, that this is not completely true. Possibly the summer generation pupates in the gall, and the winter generation in the soil.
The leaves can be folded both upwards or downwards. This must imply that oviposition may occur at both sides of the leaf, upon which the leaf deforms to enclose the developing larvae.
