Liriomyza sp. 8

(Fig. 163)

Material examined. MISSOURI: Franklin Co., Gray Summit, Shaw Nature Reserve, 1.vii.2015, em. by 19.vii.2015, C.S. Eiseman, ex Campanula americana, #CSE1709, CNC 564681 (1♀).

Host. Campanulaceae: Campanula americana L.

Leaf mine. (Fig. 163) Linear; whitish, greenish, or brownish; centered on the midrib or rarely a lateral vein.

Puparium. Brown; formed outside the mine.

Comments. We have found similar leaf mines in Iowa and Ohio. Spencer (1969) reported what was probably the same mine on Campanula americana in Ontario, the only difference being that there were short lateral offshoots from the midrib into the leaf blade. He obtained Liriomyza puparia from these but was unable to rear adults. Apart from our single poor female specimen, no North American leafminer has been reared from Campanula.
