Eiseman, Charles S. & Lonsdale, Owen, 2018, New state and host records for Agromyzidae (Diptera) in the United States, with the description of thirty new species, Zootaxa 4479 (1), pp. 1-156 : 15

Agromyza sp. 1

( Fig. 80 )

Material examined. OHIO: Delaware Co., Sunbury , Monkey Hollow Rd. , 1.viii.2016, em . 26–29.viii.2016, C.S. Eiseman, ex Verbesina alternifolia , #CSE2951, CNC654471 (1♀).

Host. Asteraceae : Verbesina alternifolia (L.) Britton ex Kearney.

Leaf mine. ( Fig. 80 ) Green, beginning at the leaf margin near a cluster of feeding punctures produced by the adult female’s ovipositor; five larvae feeding together, forming a gradually widening blotch. The larvae fed side by side throughout their development, following the leaf margin to the apex, all the way down to the base of the leaf on the other side, then reversing direction and feeding immediately adjacent to the existing mine. Frass is initially diffuse, later in dark, closely spaced small lumps and short streaks.

Puparium. Yellowish-brown to reddish-brown; formed outside the mine.

Comments. No Agromyza has been associated with Verbesina previously. This species will likely prove to be A. ambrosivora or A. virginiensis Spencer.
