Liriomyza smilacinae Spencer

( Fig. 152 )

Material examined. MAINE: Hancock Co., Castine, Rene Henderson Preserve, 21.vi.2014, em. 4.vii.2014, C.S. Eiseman, ex Maianthemum canadense , #CSE1151, CNC384888 , CNC384889 (1♂ 1♀) ; MASSACHUSETTS: Plymouth Co. , West Bridgewater, 42.007887, -71.048684, 7.viii.2013, em. 12.iii.2014, C.S. Eiseman, ex Maianthemum canadense , #CSE1002, CNC384731 (1♂) .

Host. Asparagaceae : Maianthemum canadense Desf. , M. stellatum (L.) Link, M. trifolium (L.) Sloboda, “ False Solomon’s Seal ” (= M. racemosum (L.) Link?) ( Spencer 1969; Lonsdale 2017).

Leaf mine. ( Fig. 152 ) Whitish, upper surface, entirely linear; frass in a nearly continuous black line. The mines from which we reared these specimens were contorted at the beginning, forming an elongate spiral.

Puparium. Orange; formed outside the mine.

Distribution. USA: CA, *MA, *ME; Canada: AB, MB, NB, NS, ON, QC.

Comments. The type series was reared from larvae collected in Alberta and Manitoba on June 16, June 29, and July 15. Our rearing records indicate this species is at least bivoltine in New England, with larvae occurring in June and early August. A larva collected in early July proved to be another species ( Liriomyza sp. 1, below). The only Liriomyza mines we have found on Maianthemum racemosum were already empty at the end of May.
