Leaf-mine: Larva forming linear-blotch mine between two veins, not adjoining margin of leaf, frass in distinct black strips or pellets (Spencer, 1972b: 37 (fig. 111), 39; Spencer, 1976: 100 (fig. 146)). The mine is illustrated in British leafminers and Nederlandse bladmineerders. Mine of Agromyza anthracina on Urtica dioica.
