NEPETA. Cat-mint. [Lamiaceae]
Four species of Nepeta are recorded in Britain. These include the native Cat-mint (N. cataria) and the introduced Garden Catmint (N. nepetella). Only one dipterous miner, Phytomyza obscura, is recorded on Nepeta in Britain. See CLINOPODIUM. The agromyzids Liriomyza sativae and Liriomyza trifolii, polyphagous pest species of ornamental and vegetable crops occasionally intercepted at UK points of entry, are recorded on Nepeta. Liriomyza trifolii has been found under glass in England and Wales. All populations have been and continue to be eradicated.	Garden Catmint - Nepeta nepetella
Elsewhere the agromyzids Liriomyza sativae, Liriomyza strigata, Liriomyza trifolii and Ophiomyia labiatarum are recorded mining Nepeta. One non-dipterous miner is recorded on Nepeta in Britain.
