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

1 > Leaf-miner: A
white mine along mid-rib, with offshoots into leaf blade. Pupation
internal at base of mid-rib.
In
Asteraceae the larva mostly lives as a borer in the midrib of the
leaves. From there short corridors are made into the blade. Also
a corridor can be made overlying the midrib. In Euphorbia a small mine is made in the bracts of the inflorescence. The final
mine strongly resembles the one of Liriomyza strigata, but the branches
are vritually free from frass; this is acccumulated in the resting
place of the larva, in the base of the midrib. There also pupation
takes place.
Forms a mine along the midrib and has feeding spurs into the leaf. Pupation is in the mine at the base of the midrib. |

On Cicerbita, Leontodon, Sonchus and Taraxacum, but not yet on Urospermum, in Britain
and numerous other genera of Asteraceae elsewhere. Widespread
in south, but not common, in Britain. Widespread in continental
Europe.
