Liriomyza sp. 5

( Fig. 162 )

Material examined. MASSACHUSETTS: Bristol Co., Easton , 42.006363, -71.086379, 12.viii.2013., em. 30.viii.2013, C.S. Eiseman, ex Mikania scandens , #CSE851 (1♀) ; same collection data, em. 11.iv.2014, #CSE1073, CNC384795 (1♀).

Host. Asteraceae : Mikania scandens (L.) Willd.

Leaf mine. ( Fig. 162 ) Entirely linear; long and whitish with fairly long, black, squiggly lines of frass deposited on alternating sides. The mine is typically on the underside for a considerable distance before switching to the upper surface, and in some cases it switches back and forth twice. A few of the mines we observed were at the leaf tips, and these were tightly convoluted, forming secondary blotches.

Puparium. Yellowish; formed outside the mine. One was found attached to the underside of a leaf, which was a useful adaptation given that a larva dropping from these leaves would have drowned in standing water.

Comments. Several Liriomyza have been reared from Mikania , including species known from the Nearctic— L. sativae ( Martinez 1993) , L. eupatorii , and one unidentified species in Florida ( Diaz 2015) —but our females cannot currently be associated with any of these with confidence.
