Phytomyza View in CoL View at ENA sp. 6

( Fig. 222 View FIGURES 217–224 )

Material examined. OREGON: Clackamas Co., Mt. Hood / Mirror Lake , 14.x.2012, em. 28.iv–5.v.2013, C.S. Eiseman, ex Trautvetteria caroliniensis , #CSE375, CNC422924–422935 View Materials (12♀) .

Host. Ranunculaceae : Trautvetteria caroliniensis (Walter) Vail.

Leaf mine. ( Fig. 222 View FIGURES 217–224 ) Multiple larvae feed together, making contorted mines that initially have squiggly, stringy frass; later frass is deposited in discrete grains.

Puparium. Brownish; formed within the mine.

Comments. Larvae were still active in mid-October at the time of collection. Unfortunately all 12 adults reared from these mines were females. These have a yellow frons, face, knees, and shoulders, as well as equal-sized ors, similar to Phytomyza plumiseta Frost , but are not readily identified to this or other known species with these features. Trautvetteria is not a known host for any agromyzid.

Phytomyza sp. 7

( Fig. 223 View FIGURES 217–224 )

Material examined. OREGON: Clackamas Co., Mt. Hood / Mirror Lake, 14.x.2012, em. by 30.iv.2013, C.S. Eiseman, ex Tiarella trifoliata var unifoliata , #CSE378, CNC 384814 (1♀).

Host. Saxifragaceae : Tiarella trifoliata L. var. unifoliata (Hook.) Kurtz.

Leaf mine. ( Fig. 223 View FIGURES 217–224 ) Long, linear, whitish, on the upper leaf surface; frass in discrete black grains, widely spaced except near the beginning.

Puparium. Whitish with a dark, central, longitudinal stripe; formed within the leaf, in a small chamber on the lower surface, with the anterior spiracles projecting through the lower epidermis.

Comments. The mine may not be distinguishable from that of Phytomyza tiarellae , which is also known from Tiarella trifoliata , although some of the mines at the collection site were substantially wider at the end than 2 mm, the approximate terminal width given for that species by Griffiths (1972a). Also see comments for P. tigris .
