ECHINOPS. Globe Thistles [Asteraceae]

Five species of Echinops are recorded in Britain. All species are introduced and include Blue Globe-thistle (E. bannaticus) and Glandular Globe-thistle (E. sphaerocephalus). Two dipterous miners, the agromyzids Chromatomyia 'atricornis' and Phytomyza bipunctata, are recorded on Echinops in Britain. Elsewhere the agromyzids Chromatomyia 'atricornis' and Phytomyza bipunctata are recorded mining Echinops. No non-dipterous miners are recorded on Echinops in Britain.

Key for the identification of the known Diptera mines in Britain.
