The nettle pouch gall develops in leaf veins, leaf petioles, flower stalks and sometimes the stem of Urtica dioica (and less commonly Urtica urens). This structure is caused by the gall midge Dasineura urticae, sometimes misspelled Dasyneura urticae. Obsolete synonyms are Perrisia urticae and Cecidomyia urticae. Wikipedia →
