 Hosts. Urticaceae: Urtica spp., Parietaria L.; Cannabaceae: Cannabis L., Humulus L.; Mentzelia Plum. ex L. ( Spencer 1976).   
 Mine. The larva forms a greenish-black full-depth blotch mine. In the early stage it is located mainly along the leaf margin and then can spread to occupy the whole leaf (depending on the leaf size). Three larvae feed together in one mine. Pupation takes place outside the mine in the soil.   
 Puparium. (Figs. 16–18) Reddish-brown, glossy, 3.2 mm long, with deep segmentation; surface quite smooth except for spine bands. Both posterior spiracles set on one stout conical protuberant mounting; brown, with three strong orange bulbs set in a circular configuration at acute angles to each other. Anal plate black, not protruding above the surface of the puparium viewed from the side and directed ventro-posteriorly.   
 Cephalopharyngeal skeleton. (Figs. 300, 301) Both mouthhooks equal in size and shape, rounded ventrally. Each mouthhook bears two sharp accessory teeth. Intermediate sclerite long and narrow, 1.16× as long as height of mouthhook. Straight parastomal bar exist. Dorsal and ventral cornua bear wide and long “closed” windows. Intermediate sclerite strongly sclerotized only in dorso-anterior half. The pharyngeal sclerite is much more sclerotized ventro-anteriorly. Indentation index 83. See also in Sasakawa (1961: Fig. 11 l).   
 Female head. (Figs. 302, 303) Black, with orbit not projecting above eye in profile, 2 orb s, 3 fr s and low, largerly semicircular lunule, reaching the level between 2 nd and 3 rd fr s; pped elongated, flattened ventrally with white pubescence; gena medially 0.1× as high as maximum height of eye.   
 Female genitalia. (Fig. 304) Spermathecae unequal in size, brown, with corrugated surface, flattened basally, with wide and shallow internal duct invagination. Neck of spermatheca narrow and strongly sclerotized. Shape of capsule of spermatheca can be rounded, trapezoid or rectangular. Proctiger and egg guide see in Sasakawa (1961: Fig. 11 h, g).   
 Distribution. Extremely widely distributed species known from the Palaearctic, Nearctic, and Oriental Regions (Papp & Černý 2015; Eiseman & Lonsdale 2018; Černý & Roháček 2020). Also widespread in Ukraine (Guglya 2011, 2012, 2015, 2016, 2017, 2020).
