Life cycles

Monoecious holocyclic  

Host plants

Ribes nigrum, blackcurrant; Ribes rubrum, redcurrant; and Ribes alpinum, alpine currant.

Particular characteristics

The presence of spring colonies prevents the growth of shoots and causes deformations in leaves which curl up to form nests of leaves actively visited by ants.

The species stays on its hosts all year.
