AETHIONEMA. Candytufts. [Brassicaceae]
|
Two
species of Aethionema, Persian Candytuft (A. grandiflorum)
and Burnt Candtuft (A. saxatile), are recorded in Britain.
Both are introduced.
Only one British miner is recorded on Aethionema.
A key to the European miners recorded on
Aethionema is provided in Bladmineerders van Europa.

insects (Diptera and non-Diptera) recorded on Aethionema

1a > Leaf-miner: Mine linear, whitish, both upper and lower surface. Pupation internal,
at the end of the mine with the anterior spiracles projecting through
the epidermis (Spencer, 1976:
433).
Upper-surface,
less often lower-surface corridor. Frass in isolated grains. Pupation
within the mine, usually in a lower-surface puparial chamber.
A long whitish upper surface corridor, which eventually goes lower surface. |

Two
highly polyphagous species of Chromatomyia, with indistinguishable
mines, have been recorded in Britain. These are syngenesiae (Hardy) and horticola (Goureau) which can only be distinguished by the male genitalia. Both species are widespread in Britain and elsewhere, although syngenesiae is almost entirely restricted to Asteraceae. Records on Asteraceae not based on examination of male genitalia are treated in this account as Chromatomyia 'atricornis'.
Chromatomyia horticola is recorded on 160 plant genera in 31 families of which 55 plant
genera in 19 families, but not yet on Aethionema, in Britain. On Aethionema elsewhere.
