Ophiomyia abutilivora Spencer

( Figs. 64–65 )

Material examined. IOWA: Winneshiek Co., Decorah, Trout Run Trail , vii.2017, em. by 26.vii.2017, J. van der Linden, ex Abutilon theophrasti , # CSE4940 , CNC1643668–1643669 (1♁ 1♀) .

Hosts. Malvaceae : Abutilon theophrasti Medik. ; adults have been collected on flowers of Sida cordifolia L. ( Spencer & Steyskal 1986).

Larval mine. ( Figs. 64–65 ) The larva mines up and down the stem, forming an irregular, gall-like “welt” and associated scarring.

Puparium. Whitish to yellowish; formed within the stem, with the anterior spiracles projecting through the epidermis.

Phenology and voltinism. The only reared specimens in the type series are from Mississippi with a date of 22 October; whether this was the collection or emergence date was not stated, but either way they would seem to represent a different generation from our Iowa specimens, which emerged from green stems in late July. Adults have been collected in August and September in Minnesota, and in March in Florida ( Spencer & Steyskal 1986) .

Distribution. USA: FL, *IA, [IL], MN, MS, [WI] ( Spencer & Steyskal 1986).
