Agromyzid fly
ID based on the frass and the fact that many agromyzid fly larvae make a linear mine in their first two instars and a blotch in their final instar. You may be able to determine the species using one of these resources:
Spencer, Kenneth A. and George C. Steyskal. Manual of the Agromyzidae (Diptera) of the United States. United States Department of Agriculture, Agricultural Research Service, Agriculture Handbook Number 638, 1986.
Spencer, Kenneth A. Host Specialization in the World Agromyzidae (Diptera). Boston: Kluwer Academic Publishers, 1990.
If not, you'd have to rear the larvae out. Fewer than half of the hundreds of North American agromyzids have been linked to a host plant, so there are many mines that cannot be identified to species level at this point.
