The larvae of the fly Phytomyza angelicae mine the leaves of Wild Angelica (Angelica sylvestris). The larva forms an upper surface primary oval or circular blotch with several larvae feeding together; the blotch is greenish when fresh but becomes yellowish with age.
Mines occur mainly on Wild Angelica leaves, occasionally on Ground-elder.
The leaf mines can be seen when the host plants are in leaf.
Widespread in Britain, but not well recorded.
Status in Leicestershire and Rutland not known.
