Hosts. Iridaceae : Iris pseudacorus L. ( Spencer 1976), I. cristata Aiton ( Eiseman & Lonsdale 2018) , Gladiolus Tourn. ex L. and Typhaceae : Typha L. ( Warrington 2021).
Mine. ( Figs. 89 View FIGURES 84–93 ) The larva forms a white linear mine on the upper side of the leaf. Frass normally appearing as a single black spot several (2–5) centimetres from puparium. Pupation takes place within the mine ( Fig. 90 View FIGURES 84–93 ).
Puparium. ( Figs. 91–93 View FIGURES 84–93 ) Orange viewed from above, reddish-brown viewed from the side and black viewed from below, glossy, 2.7 mm long, with weak segmentation; surface wrinkled except for wide spine bands. Both posterior spiracles orange, tube-shaped, set on a single wide trapezoidal protuberance in posterior view. Posterior spiracles viewed from the side are depicted in Nowakowski (1973: Fig. 260 View FIGURES 253–260 ). Anal plate slightly protruding above the surface of the puparium viewed from the side and directed posteriorly.
Cephalopharyngeal skeleton. ( Fig. 412 View FIGURES 412–420 ) Right mouthhook larger than the left, both with long finger-like abducted portion directed ventro-posteriorly. Each mouthhook bears two apically rounded accessory teeth. Intermediate sclerite long, narrow and waved, 1.33× as long as maximum height of the left mouthhook. The mouthhook and intermediate sclerite are strongly sclerotized, the pharyngeal sclerite much less so. Indentation index 84. See also in Nowakowski (1973: Fig. 218 View FIGURES 211–220 ), Sasakawa (1961: Fig. 56 l View FIGURES 45–57 ).
Female head. ( Figs. 413, 414 View FIGURES 412–420 ) Yellowish-black, with antenna, palpus, oc tr and postgena black, proboscis yellow; orbit not projecting above eye in profile, 2 orb s, 2 fr s; lunule semicircular, reaching the level between fr s; pped large, flattened ventro-anteriorly; gena medially 0.15× as high as maximum height of eye.
Female genitalia. ( Fig. 415 View FIGURES 412–420 ) Spermathecae equal in size, brown, concave apically, mushroom-shaped, 0.3× as high as maximum width. Neck of spermatheca conical, wider than long, narrowed in the direction of duct, 0.35× as long as maximum width. Spermathecal duct wide, crested, weakly sclerotized. Proctiger see in Sasakawa (1961: Fig. 56 h View FIGURES 45–57 ).
Distribution. Widespread in Europe, Japan and South Korea ( Papp & Černý 2016); tentatively recorded from USA ( Eiseman & Lonsdale 2018). Ukraine (first record).
