DIGITALIS. Foxgloves. [Scrophulariaceae]


Five species of Digitalis are recorded in Britain. These include the native Foxglove (D. purpurea).

One British miner is recorded on Digitalis.

The agromyzid Napomyza scrophulariae is recorded feeding in both seed heads and stems of Digitalis pupurea and possibly Scrophularia nodosa, Verbascum and Mentha in Britain.

A key to the European miners recorded on Digitalis is provided in Bladmineerders van Europa.

insects (Diptera and non-Diptera) recorded on Digitalis


1a > Leaf-miner: Rather long full depth corridor that winds freely through the leaf and may cross itself. In the end the corridor widens considerably. Frass mostly in a narrow central line, but may also be deposited along the sides or be missing. The larvae regular leave a mine to restart elsewhere. Pupation outside the mine. Neither larva or mine can be distinguished from that of related species.

Polyphagous. On numerous genera and species in several plant families, including Digitalis, in Britain. On numerous genera and species in several plant families, including Digitalis, elsewhere. Widespread in Britain and continental Europe.

Apteropeda orbiculata (Marsham, 1802) [Coleoptera: Chrysomelidae].
