Biology and notes: The orange larvae develop in leaf galls on Filipendula ulmaria and F. lobata ( Rosaceae). Our records are all from F. ulmaria . Each larva develops in a small gall which forms a small dome on the upper side of the leaf and projects nozzle-like on the underside. Multivoltine. Pupation is known to take place inside the gall, but we have on several occasions also had mature larvae evacuating the galls and burrowing into the soil to pupate.

Distribution: Widespread in Europe including Norway, Sweden, Denmark and Finland. Russia to the Far East.
