Host.* Poaceae: Elymus hystrixL. Leaf mine.( Fig. 66) In the single example observed, three eggs were inserted in a cluster in the basal portion of a leaf, near the middle, and the larvae mined distally, forming gradually widening tracks that eventually merged. In the young mines, black frass particles formed two rows, delineating a green central area; the margins of the mines were whitish.
Puparium.Reddish-brown; formed outside the mine.
Distribution. USA: GA, *IA, MD, NC, NY, UT, VA; Canada: ON.
Comments. Spencer (1969)reported a broad, white mine, up to three inches long, produced by an unidentified Agromyzaspecies on Elymus hystrixin Ontario. Otherwise, the only previous record of an Agromyzaspecies on Elymusis that of A. ambiguaFallén(as A. niveipennisZetterstedt) from E. repens(L.) Gould (as Agropyron repens(L.) Beauv.) ( Frick 1959; Spencer & Steyskal 1986).
