Liriomyza View in CoL sp. 2

( Fig. 159 View FIGURES 154–164 )

Material examined. MASSACHUSETTS: Middlesex Co., Newton, near Waltham line, 21.vi.2014, em. by 23.vi.2014, J. F. Carr, ex Ageratina altissima , #CSE1136, CNC 384895 (1♀).

Host. Asteraceae : Ageratina altissima (L.) R.M. King & H. Rob.

Leaf mine. ( Fig. 159 View FIGURES 154–164 ) Entirely linear; long, narrow and whitish, with very little visible frass (a few minute grains and irregular thread fragments); 1.5 mm wide at the end.

Puparium. Yellowish, formed outside the mine. The puparium of the single reared specimen was glued with black frass to the lower leaf surface, as we have observed in Liriomyza eupatoriella .

Comments. Spencer & Steyskal (1986) reported that empty mines of an unidentified agromyzid were common on A. altissima in Minnesota, Wisconsin, and Washington, DC in late June and early July. They stated that the mine “is long, narrow, with scarcely perceptible frass, frequently with several mines in the same leaf. It is probably caused by a Phytomyza sp.” They did not indicate how this mine differed from that of Liriomyza eupatoriella Spencer , which was reared from a “long, narrow linear mine” on the same host in Wisconsin in September, but there appears to be frass in the illustrated mine. They listed observations of empty mines of L. eupatoriella from the same dates and locations as the unidentified mines. Our impression, from examining numerous linear mines on A. altissima , is that mines with and without visible frass represent a continuum rather than two distinct categories. Our female specimen was associated with a mine that was certainly at the “scarcely perceptible frass” end of the continuum.

Based on examined specimens and published descriptions, our female differs from L. eupatoriella most noticeably in having a strong yellow stripe across the posterior margin of the scutum (not narrowly connected medially by a black extension), the calypter is widely grayish along the outer margin and the sides of the abdomen appear to be more widely yellow.
