Hosts. Campanulaceae : Campanula L., Jasione L., Phyteuma L..; Asteraceae : Crepis L., Hieracium L., Hypochoeris L., Lapsana L., Leontodon L., Matricaria L., Mycelis Cass. (syn. Lactuca L.), Prenanthes L., Reichardia Roth , Scorzonera L., Sonchus L., Tragopogon L. ( Benavent-Corai et al. 2005).

Mine. ( Fig. 22 ) The larva feeds as an external stem miner. Frass is arranged in narrow widely spaced lines. Mine tunnels, larva and puparium are well visible from outside. Pupation takes place subepidermally.

Puparium. ( Figs. 23, 24 ) Dark yellow except the black interosegmental bands, 3.0 mm length, with readily visible but shallow segmentation; surface quite smooth except for bands consisting of a single row of large spines and 3–4 rows of minute spines between all segments. Posterior spiracles yellowish-black, set on short stout cylindrical protuberances that are entirely separated; dark yellow or brown, fan-shaped, with 11–15 sessile bulbs arranged in irregular row. Anal plate brown, with clear contours, protruding above the surface of puparium viewed from the side and directed ventro-posteriorly.

Cephalopharingeal skeleton. ( Fig. 151 ) Right mouthhook larger dorsally and slightly smaller ventrally than the left, both with ventro-anterior portion acute; right abducted anteriorly, left abducted ventrally. Both mouthhooks bear two accessory teeth; both dorsal teeth are large, both ventral are small, all sharp, uniformly curved ventrally. Both dental sclerites well developed, equal in size, strongly curved, long, 1.25× as high as left mouthhook. Mouthhooks, posterior half of dental sclerites and intermediate sclerite are strongly sclerotized, dorsal cornua and ventral cornua much less so. Intermediate sclerite straight, uniformly widening posteriorly. Indentation index 85.

Female head. ( Figs. 148, 149 ) Black, with fronto-orbital plate not visible laterally; 2 ors, 2 ori; 1 st fl small, oval. Gena narrower at rear, 0.15× as wide as maximum height of eye. Vibrissa of medium length, straight, directed ventro-anteriorly, 0.32× as long as maximum height of eye. Facial carina of medium size, elongated, with distinct furrow in medial bulb, 0.26× as wide as minimum width of frons.

Wing. ( Fig. 150 ) Hyaline, with greyish undertone, with costa black and the remain veins brown; costa ending after R 3+4; last section of CuA 1 1.1× as long as penultimate; calypter brown, margin and fringe black. Wing length 2.0 mm.

Female genitalia. ( Fig. 152–154 ) Spermathecae of medium size, 0.24× as high as anterior part of oviscape. Blade of egg-guide relatively wide, 3.2× as long as maximum width, acute apically, with medial membrane without any scales. Outer marginal denticles fine, scarcely visible, directed lateroposteriorly. Proctiger generally cylindrical, tapered in the middle. Cercus oval, flattened apically, 0.2× as long as proctiger; patches of long setae located internalaterally and short setae apically. Spermathecae equal in size, brown, slightly wider than high and flattened basally. Internal duct invagination 0.8× as deep as height of spermatheca, narrowing medially. Distinct basal collar present. Spermathecal duct weakly sclerotized.

Distribution. Austria, British Isles, the Czech Republic, Finland, France, Germany, Hungary, Italy, Latvia, Lithuania, Poland, Slovakia, Sweden, Switzerland ( Papp & Černý 2015). Ukraine (first record).
