CATABROSA.
[Poaceae]
|
One
species of Catabrosa is recorded in Britain. The BSBI provide a downloadable plant cribs for the identification of species of Catabrosa.
Only one British miner is recorded on Catabrosa.
Nearly 100 British miners or possible miners are recorded on grasses in Britain.
A key to the European miners recorded on Catabrosa is provided in Bladmineerders van Europa.
It is recommended that adults of all miners on grasses be reared to be certain of their identity. |

Leaf miner: A substantial linear mine. Pupation internal; posterior spiracles
projecting through the epidermis (Spencer,
1976: 449).
Elongated,
shallow, upper-surface or lower-surface blotch, not infrequently
several in one leaf. Frass in strings or pearl chains. Pupation
within the mine. |

On Hierochloe, Holcus, Hordeum, Milium and Poa, but not yet on Catabrosa, in Britain
and additional genera of grasses elsewhere. Almost certainly widespread
throughout the British Isles. Also recorded in the Republic of
Ireland. Widespread from Morocco through central and northern
Europe.
