Hosts. Asteraceae : Solidago * altissima L. , S. * canadensis L. , S. * latissimifolia Mill., S. * sempervirens L. We have seen probable mines of this species on S. gigantea Aiton , S. juncea Aiton , S. odora Aiton , S. rugosa Mill. , S. speciosa Nutt. , and S. ulmifolia Muhl. ex Willd. , as well as on Oligoneuron rigidum (L.) Small (formerly S. rigida L.).

Leaf mine. ( Fig. 118 ) Whitish, initially linear, expanding into a blotch that proceeds apically along the leaf margin. Occasionally the linear portion is obliterated by the blotch. Frass is brown and diffuse, forming a central line in the linear portion.

Puparium. Brown; formed within the mine, glued to a lump of frass on the floor.

Distribution. Throughout the USA; Canada: NS, ON, QC, YT ( Boucher & Wheeler 2001); Europe.
