( Figs. 76–77 View FIGURES 75–82 )
Material examined. IOWA: Winneshiek Co., 43°26'32.50"N, 92°0'10.32"W, 17.vii.2015, em. 13.viii.2015, C.S.

Eiseman, ex Heliopsis helianthoides , #CSE2846, CNC654189–654193 View Materials (1♂ 4♀) ; OHIO: Delaware Co., Sunbury, Monkey Hollow Rd. , 20.vii.2015, em. 7–17.viii.2015, C.S. Eiseman, ex Heliopsis helianthoides , #CSE1972, CNC564733–564745 View Materials (3♂ 9♀ 1 unemerged from puparium).
Hosts. Asteraceae : * Heliopsis helianthoides (L.) Sweet, Rudbeckia L. ( Scheffer & Lonsdale 2018). The “undetermined yellow-flowered composite” illustrated by Scheffer & Lonsdale appears to be Heliopsis helianthoides .
Leaf mine. ( Figs. 76–77 View FIGURES 75–82 ) Greenish, turning brown; a blotch mine that may be compact or narrow and elongate, in the latter case following the leaf margin; frass diffuse. Scheffer & Lonsdale (2018) stated that the mine starts at the leaf apex, but this is not always the case. Up to four white larvae may feed in a single mine.
Puparium. Brown; formed outside the mine.
Distribution. USA: *IA, *MA, NY, *OH, VT ( Scheffer & Lonsdale 2018).
Comments. Scheffer & Lonsdale (2018) collected larvae from Rudbeckia in June and adults emerged after overwintering. All of our specimens were collected as larvae in July and adults emerged within a month. Larvae from all three collection sites were observed to exit their original mines and establish new ones elsewhere ( Fig. 77 View FIGURES 75–82 ). The ability to do so is common in other leaf-mining flies ( Anthomyiidae , Drosophilidae , Ephydridae ), but in five years of rearing we have observed it in Agromyzidae on just one other occasion. This was on Hackelia virginiana (L.) I.M. Johnst. ( Boraginaceae ) in Dutchess Co., New York on 22 June 2013; unfortunately we were unable to rear adults. Phytomyza ovalis Griffiths is the only agromyzid recorded from Hackelia , but it is not known to occur east of Colorado. A group of Agromyza species is associated with Boraginaceae and the New York Hackelia feeder may be one of these.
