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.
