Seven
species of Gentiana are recorded in Britain. These include
the native Alpine Gentian (G. nivalis), Marsh Gentian (G.
pneumonanthe) and Spring Gentian (G. verna).
Alpine
Gentian (G. nivalis) and Spring Gentian (G. verna)
are protected under Schedule 8 of the Wildlife and Countryside Act,
1981.
Spencer
(1972b: 95) recorded Chromatomyia
gentianae (as Phytomyza) on Blackstonia
perfoliata and Centaurium
erythrae (as minus). However, he later (Spencer,
1990: 396-7) recognised that specimens on Blackstonia
perfoliata and specimens on Centaurium
erythrae represented two different new species, which he described
as Chromatomyia
blackstoniae and Chromatomyia
centaurii respectively.
Chromatomyia
gentianae is not a British species. It is recorded elsewhere
on Gentiana and Gentianella.
Elsewhere
the agromyzids Liriomyza
bryoniae and Liriomyza
huidobrensis are recorded mining Gentiana.
One
non-dipterous miner is recorded on Gentiana in Britain.
