Phytobia[1] is a genus of flies on the family Agromyzidae,[2][3] with a worldwide distribution principally in Europe and the Americas.
As with many Agromyzidae, species of Phytobia are typically leaf miners on various plants, although other plant parts may be attacked. For example, P. betulae lays its eggs on the bark of new-growth twigs of suitable birch trees and, after hatching, larvae tunnel downwards along the shoot within the differentiating xylem layer, sometimes reaching the base of the tree. Adults are small-medium-sized flies (approximately 5 mm in the case of P. betulae).[4]
