PANICUM.
Millets. [Poaceae]
|
|
Twenty-one
species of Panicum are recorded in Britain. All are introduced.
Only one British miner is recorded on Panicum.
Nearly 100 British miners or possible miners are recorded on grasses in Britain.
A key to the European miners recorded on Panicum is provided in Bladmineerders van Europa.
It is recommended that adults of all miners on grasses be reared to be certain of their identity. |

1 > Leaf-miner: Irregular
mine, locally shallow, elsewhere much deeper, giving it a mottled
appearance. In broadleaved plants the mine often begins as a blotch
with stellate extensions, but sometimes as a very fine, shallow
corridor. In grasses the mine often begins in the leaf sheath. The
frass is very fine-grained, initially scattered, later in aggregates. |
