SANTOLINA.
[Asteraceae]
|
Two
species of Santolina are recorded in Britain. Both are introduced.
Only one British miner is recorded on Santolina.
A key to the European miners recorded on Santolina is provided in Bladmineerders van Europa.

1 > 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, in a, usually lower-surface, pupal 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 atricornis is recorded on Santolina elsewhere but not yet on Santolina in Britain.
