Nine
species of Setaria are recorded in Britain. All are introduced
and include Adherent Bristle-grass (S. adhaerens), Nodding
Bristle-grass (S. faberi), Foxtail Bristle-grass (S. italica),
Yellow Bristle-grass (S. pumila), Rough Bristle-grass (S.

Bristle-grass (S. parviflora).
Only
one species, the agromyzid Agromyza
nigrella, is recorded on Setaria in Britain. Miners
on grasses should be reared, whenever possible, to confirm their
identity.
