Biology and notes: The orange larvae develop gregariously in leaf rolls on Tilia spp. ( Malvaceae). The leaf margin is rolled upwards along part of the leaf and is often miscolored red. Univoltine; pupation and hibernation in the soil. We have on several occasions found white larvae of Macrolabis sp. living together with the orange larvae of Dasineura tiliae . These may represent an undescribed species.

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