Leaf-mine: A white linear-blotch mine, the linear section sometimes not detectable as it becomes enveloped in later blotch (Spencer, 1976: 162-3, figs 296-7). The mine is illustrated in British leafminers and Nederlandse bladmineerders. Mines of Amauromyza flavifrons on Silene dioica. Image: Willem Ellis (Source: Nederlandse bladmineerders) Larva: The larva is described by Ellis (Nederlandse bladmineerders). Puparium: Reddish brown; posterior spiracles each with 3 bulbs (Spencer, 1976: 162). Comments: Records of flavifrons on Glechoma [Lamiaceae] (Robbins, 1991: 103; Pitkin, in Pitkin & Plant, 2005) [Lamiaceae] are doubtful and require confirmation. In England flavifrons occurs commonly in gardens on Dianthus species (Spencer, 1976: 163).
