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 : 16

Agromyza sp. 6

Material examined. MASSACHUSETTS: Nantucket Co., Nantucket , Nantucket Conservation Foundation Bird Sanctuary ( North Beach St. ), 11.vi.2013, em. 21–27.iii.2014, C.S. Eiseman, ex Rosa multiflora, #CSE1016, CNC384739–384741 (3♀) .

Host. Rosaceae : Rosa multiflora Thunb.

Leaf mine. Greenish to pale brownish upper surface linear-blotch, with frass in scattered particles (forming two rows in the linear portion) and irregular lumps.

Puparium. Brown; formed outside the mine.

Comments. These three females may represent the normally bivoltine Agromyza idaeiana Hardy , which is recorded from Rosa spp. in Europe ( Ellis 2016), but it is conceivable that they belong to a distinct, strictly univoltine species.
