The larvae of the fly Phytomyza angelicastri mine the leaves of Wild Angelica and Ground Elder. This can be a variable leafmine though often linear, following the leaf margin but sometimes creating a blotch mine on the upper leaf surface.

See the National Agromyzidae Recording Scheme webpage for this species for further details of puparium and adult insect.

Phytomyza angelicae, Phytomyza archangelicae, Phytomyza chaerophylli and Phytomyza obscurella can all form identical mines.
