 Hosts. Poaceae: Agropyron Gaertn., Dactylis L., Hordeum L., Secale L., Triticum L. (Benavent-Corai et al. 2005), Phalaris L., Phragmites Adans. (Nowakowski 1973), Agrostis L., Apera Adans., Elymus L. (Warrington 2021). Lolium pratense (Huds.) Darbysh and Milium effusum L. are newly recorded host plants.   
 Mine. (Fig. 97) The larva forms a white linear mine near the leaf margin in a wide leaf, or a blotch in a narrow leaf. The mine can be seen equally well from both leaf sides and may contain one or two larvae. Pupation takes place within the mine.   
 Puparium. (Figs. 98, 99) Black, mirror-shining except two last abdominal segments, which are matt and finely folded; 2.2 mm long, with deep segmentation; surface smooth except for narrow wrinkled spine bands. Both posterior spiracles are set on a single wide protuberance flattened dorso-ventrally; brown, glossy, two-horned and entirely separate. The puparium (viewed from the side and above) and posterior spiracles are depicted in Nowakowski (1973: Figs. 231). Anal plate strongly protruding above the surface of the puparium viewed from the side and directed dorso-posteriorly.   
 Cephalopharyngeal skeleton. (Fig. 421) Right mouthhook larger than the left, both angulate ventrally. Each mouthhook bears two sharp accessory teeth. Intermediate sclerite narrow, straight, 1.26× as long as maximum height of left mouthhook. The mouthhook and intermediate sclerite are strongly sclerotized, pharyngeal sclerite much less so. Indentation index 85. See also in Nowakowski (1973: Fig. 50 l).   
 Female head. (Figs. 422, 423) Yellowish-black, with proboscis and dorsal half of frons bright yellow, antenna, oc tr and postgena black; orbit not projecting above eye in profile, 2 orb s, 2 fr s; lunule narrow, semicircular, reaching the level of the posterior fr s; pped of medium size, slightly longer than high; gena medially 0.16× as high as maximum height of eye.   
 Female genitalia. (Fig. 424) Spermathecae equal in size, dark brown, oval, asymmetrical, without basal collar, 1.45× as wide as height. Entire surface of capsule irregularly furrowed dorso-ventrally. Neck of spermatheca conical, wider than long, narrowing in the direction of duct, 0.45× as long as maximum width, with additional narrow rim-shaped sclerotization slightly distanced. Spermathecal duct weakly sclerotized. Proctiger see in Sasakawa (1961: Fig. 50 h).   
 Distribution. Widespead Palaearcrctic species (Papp & Černý 2016). Ukraine (Nowakowski 1973).
