Biology and notes: The white larvae develop in leaf galls on Urtica dioica and U. urens ( Urticaceae). Our records are all from U. dioica . The base of the leaf is folded downwards to form a closed pouch. Often also other parts of the leaf blade or stem are affected. Multivoltine; pupation and hibernation in the soil. We have on several occasions found white larvae of Macrolabis sp. living together with Dasineura urticae . These may represent an undescribed species.

Distribution: Widespread Palearctic, including Norway, Sweden, Denmark and Finland.
