Liriomyza sp. 3

( Fig. 160 )

Material examined. MASSACHUSETTS: Berkshire Co., Sheffield, 9.vii.2014, em. by 28.vii.2014, C.S. Eiseman, ex Bidens frondosa , #CSE1210, CNC384879 (1♀) .

Host. Asteraceae : Bidens frondosa L.

Leaf mine. ( Fig. 160 ) Whitish, discoloring brownish; entirely linear, but contorted to form a secondary blotch that fills the apical portion of the leaf, broken here and there by slivers of intact green tissue. Frass is in a narrow, nearly continuous black trail.

Puparium. Yellowish; formed outside the mine.

Comments. Our single specimen is relatively pale in coloration and reared from Bidens , suggesting Liriomyza trifolii (Burgess) , but the female cannot be confidently identified in the absence of males. We have found very similar mines on other Asteraceae , e.g. on Ageratina altissima (L.) R.M. King & H. Rob. in Ohio and on Mikania scandens (L.) Willd. in Massachusetts.
