ANTHOXANTHUM. Sweet Vernal-grass. [Poaceae]

Three species of Anthoxanthum are recorded in Britain. These include the native Sweet Vernal-grass (A. odoratum). Two dipterous miners, the agromyzids Chromatomyia fuscula and Chromatomyia nigra, are recorded on Anthoxanthum in Britain. Miners on grasses should be reared, whenever possible, to confirm their identity. Elsewhere the grass-feeding agromyzids Cerodontha incisa and Chromatomyia nigra are recorded mining Anthoxanthum. Three non-dipterous miners are recorded on Anthoxanthum in Britain (see below).

Key for the identification of the known Diptera mines in Britain.

1> Narrow, whitish mine, with frass in distinct black lumps. Pupation internal. Puparium pale yellowish, anterior posterior spiracles projecting through the epidermis. Chromatomyia fuscula (Zetterstedt) (Agromyzidae). -> Long, narrow, whitish mine. Pupation internal. Puparium yellowish brown, anterior spiracles projecting through the epidermis. Mine of Chromatomyia nigra on Arrhenatherum elatius. Image: Willem Ellis (Source: Nederlandse bladmineerders) Chromatomyia nigra (Meigen) [Agromyzidae].
