VULPIA. Fescues. [Poaceae]


Eleven species of Vulpia are recorded in Britain. These include five native species.

Only one British miner is recorded on Vulpia.

Nearly 100 British miners or possible miners are recorded on grasses in Britain.

It is recommended that adults of all miners on grasses be reared to be certain of their identity.



Key for the identification of the known mines of British
insects (Diptera and non-Diptera) recorded on Vulpia


1 > Leaf-miner: Long, narrow, whitish mine. Pupation internal (Spencer, 1976: 453); anterior spiracles projecting through the epidermis.

Whitish, upper-surface, rather narrow corridor with comparatively large frass grains that are laying further apart than their diameter. Pupation within the mine. The anterior spiracles of the orange-brown puparium penetrate the epidermis.
