Initially some small corridors, arranged in a star, often following a vein. Later they are overun by a large primary blotch that often adheres to the leaf margin. Primary feeding lines apparent, but secondary ones not. Frass initially almost invisible, in the later blotch in big black pieces. Pupation outside the mine.

notes

Spencer (1976a) synonymized this species with Ph. angelicae. This synonymy, that is supported by von Tschirnhaus (1999a), is not accepted by Beiger (1981a) and Pakalniškis, (2000a) who note differences in the mines of both species. This matches with the findings by de Meijere (1937a). de Meijere not only remarked the mandibles of Ph. aegopodii are unusual, with two very sharp teeth, but he also explicitely mentions as a difference a dark band of fine warts over the mouth orifice in aegopodii, that is absent in angelicae. Also the Fauna Europaea treats aegopodii as a valid species.
