Agromyza bispinata Spencer View in CoL

( Fig. 66 View FIGURES 63–74 )

Material examined. IOWA: Winneshiek Co., Cresco , Cold Water Creek Rd. , 43°25'55.97"N, 92° 0'34.78"W, 16.vii.2015, em GoogleMaps . 7.viii.2015, C.S. Eiseman, ex Elymus hystrix , #CSE1973, CNC564662 (1♂).

Host. * Poaceae : Elymus hystrix L.

Leaf mine. ( Fig. 66 View FIGURES 63–74 ) 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 Agromyza species on Elymus hystrix in Ontario. Otherwise, the only previous record of an Agromyza species on Elymus is that of A. ambigua Fallén (as A. niveipennis Zetterstedt ) from E. repens (L.) Gould (as Agropyron repens (L.) Beauv.) ( Frick 1959; Spencer & Steyskal 1986).
