Hosts. Asteraceae : Solidago virgaurea L., Aster L., Erigeron L. ( Papp & Černý, 2015), Euribya divaricata (L.) G.L. Nesom, Euthamia graminifolia (L.) Nutt., Oclemena acuminata (Michx.) Greene , Solidago altissima L., S. arguta Aiton , S. caesia L., S. canadensis L., S. flexicaulis L., S. gigantea Aiton , S. latissimifolia Mill. , S. patula Muhl. ex Willd. , S. speciosa Nutt. , S. rugosa Mill. ( Eiseman and Lonsdale 2018) , Callistephus Cass. , Sonchus L., Taraxacum F. H. Wigg ( Warrington 2021) .

Mine. ( Fig. 37 ) The larva forms a white irregular linear mine mainly on the upper side of the leaf. Bionomics in Ukraine was discussed by Guglya (2013).

Puparium. ( Figs. 38–40 ) White or green, translucent, slightly shining, 3.0 mm long, with slightly visible segmentation; surface quite smooth. Posterior spiracles set on short conical protuberances that are entirely separate; beige, fan-shaped, with seven to eight sessile bulbs arranged in irregular row. Anal plate protruding above the surface of puparium viewed from the side and directed ventro-posteriorly.

Cephalopharyngeal skeleton. ( Fig. 327 ) Left mouthhook much smaller than the right, both flattened ventrally, with sharply abducted portions directed anteriorly. Each mouthhook bears two accessory teeth. Intermediate sclerite long and straight, weakly sclerotized centrally and posteriorly, 2.0× as long as height of the left mouthhook. The dorsal cornu bears a wide and long “closed” window. Ventral and dorsal cornua are sclerotized much less than the intermediate sclerite. Indentation index 69. See also in Sasakawa (1961: Fig. 38 l ).

Female genitalia. ( Figs. 328, 329 ) Blade of egg guide relatively wide, 3× as long as maximum width, acute and abducted apically, with medial membrane without any scales. Outer marginal denticles are sparse and rectangular. Spermathecae equal in size, brown, distinctly wider than high and flattened basally. Internal duct invagination 0.9× as deep as height of spermatheca, widening apically. Basal collar consists of several long, narrow lobes, arranged spirally around base of the spermatheca. Spermathecal duct very weakly sclerotized. Proctiger see in Sasakawa (1961: Fig. 38 h ).

Distribution. Holarctic species ( Eiseman & Lonsdale 2018) that is widespread in Europe ( Papp & Černý 2015). In Ukraine known from Transcarpathia, Volyn and Kharkiv Regions ( Guglya 2011, 2015, 2017).
