IMPATIENS. Balsams. [Balsaminaceae]

Only one species of Impatiens is native to Britain - Touch-me-not Balsam (I. noli-tangere). A further five have been introduced - Kashmir Balsam (I. balfourii), Balsam (I. balsami), Orange Balsam (I. capensis), Indian Balsam (I. glandulifera) and Small Balsam (I. parviflora). Only one dipterous miner, the agromyzid Phytoliriomyza melampyga, is recorded on Impatiens in Britain. Elsewhere the agromyzids Liriomyza huidobrensis and Phytoliriomyza melampyga are recorded mining Impatiens. No non-dipterous miners are recorded on Impatiens in Britain.
