Biology: The yellow to orange larvae develop gregariously in stem galls on Rubus spp. ( Rosaceae ). Our records are all from R. idaeus . The galls form large, brown, usually one-sided lumps, usually on the lower part of the stem. They are lined with black mycelium on the inside. Univoltine; pupation and hibernation within the gall. The species is considered a horticultural pest of low impact ( Trandem 2017).

Distribution: Widespread Palearctic, includ-

ing Norway, Sweden, Denmark and Finland.
