Hosts. Highly polyphagous species, recorded from 112 genera in 30 plant families (Papp & Černý 2017).

Mine. (Fig. 138, 139) Normally the larva forms an irregular linear leaf mine. When the leaf is too small (as in Gypsophila paniculata) the larva can move into the stem, making a linear external mine. Pupation takes place outside the mine.

Puparium. (Figs. 140–142) Yellow, translucent, glossy, 1.9 mm long, with distinct segmentation; surface quite smooth except for narrow spine bands. Posterior spiracles set on wide, short conical protuberances that are entirely separate; brown, with six sessile bulbs arranged in semicircle. Anal plate brown, scarcely protruding above the surface of the puparium viewed from the side and directed ventrally.

Cephalopharyngeal skeleton. (Fig. 470) Right mouthhook much larger than the left, each bearing two accessory teeth. Intermediate sclerite massive, 1.1× as long as maximum height of left mouthhook. The mouthhook, the intermediate sclerite centrally and anterior portion of the pharyngeal sclerite are strongly sclerotized; the intermediate sclerite dorsally and ventrally, and dorsal and ventral cornua are much less so. Indentation index 84.

Female head. (Figs. 471, 472) Yellowish-orange, with only arista, oc tr and hind margin of eye black; orbit distinctly projecting above eye in profile; 2 orb s, 2 fr s; lunule narrowing posteriorly, reaching the level of the anterior fr s; pped large, rounded; gena medially 0.33× as high as maximum height of eye.

Thorax viewed from the side. (Fig. 473) Mostly bright yellow, with kepst in ventral two-thirds, posterior half of mr and anatg posteriorly black; pprn dorsally, anepist ventrally, anepm medially, anatg anteriorly and mtkepst are blackish. Calypter and fringe dark yellow, margin brown. Cx 1 and cx 3 only with narrow blackish spots proximally.

Female genitalia. (Fig. 474) Ventral portion of the posterior part of the oviscape is less sclerotized medially. Capsule of spermatheca of medium size, the largest one 0.38× as high as height of anterior part of oviscape. Spermathecae unequal in size, dark brown, obovate, flattened basally, 1.35× as high as maximum width. Spermathecal duct well sclerotized immediately behind spermatheca base for a distance 1.5× as long as height of spermatheca. Proctiger see in Sasakawa (1961: Fig. 73 h).

Distribution. Palaearctic and Oriental Regions. Reported from the most countries of Europe including Turkey; Moroco, Egypt; Israel, Iraq, the Western Syberia of Russia, Turkmenistan, Nepal, India, China, Vietnam, Korea, Japan (EPPO 2021). In Ukraine seems to be common and widespread.
