Leaf-mining flies (Agromyzidae) are tiny flies whose larvae tunnel between leaf surfaces, leaving distinctive pale wandering or blotch mines visible on foliage. Different species create characteristic mine shapes that help identify both fly and host plant. They are present in virtually every plant community and are important prey for parasitic wasps.
