Eiseman, Charles S., Lonsdale, Owen, Linden, John Van Der, Feldman, Tracy S. & Palmer, Michael W., 2021, Thirteen new species of Agromyzidae (Diptera) from the United States, with new host and distribution records for 32 additional species, Zootaxa 4931 (1), pp. 1-68 : 34

Phytomyza doellingeriae Eiseman & Lonsdale

Material examined. MASSACHUSETTS: Worcester Co ., Rutland, 42.381206, -71.964980, 9.vi.2018, em. ~ 29. vi.2018, C.S. Eiseman, ex Doellingeria umbellata , # CSE4705 , CNC1135713 (1♁).

Host. Asteraceae : Doellingeria umbellata (Mill.) Nees.

Leaf mine. Whitish, upper surface, narrow, entirely linear; frass in closely spaced grains or beaded strips along the sides ( Eiseman & Lonsdale 2018).

Puparium. Blackish; formed outside the mine.

Phenology and voltinism. This species is at least bivoltine, with larvae feeding in early June in Massachusetts emerging as adults within a few weeks; in Maine, larvae have been found in late August, with adults emerging the following spring.

Distribution. USA: *MA, ME.

Comments. Phytomyza solidaginivora Spencer has been reared from larvae forming similar mines on Doellingeria umbellata in mid-June in Maine ( Eiseman & Lonsdale 2018); it therefore appears that phenology is not useful in distinguishing mines of the two species.
