Hosts. Aspleniaceae : Asplenium pinnatifidum Nutt., A. * platyneuron (L.) Britton, Sterns & Poggenb., A. rhizophyllum L.; * Pteridaceae : Pellaea atropurpurea (L.) Link, P. glabella Mett. ex Kuhn ( Frick 1959) . In Missouri we have found mines with puparia on Woodsia obtusa (Spreng.) Torr. (Woodsiaceae) in association with mines on Asplenium and Pellaea from which we reared Phytoliriomyza felti , but no adults emerged from the Woodsia mines.

Leaf mine. ( Figs. 169–170 ) A whitish to green blotch, which may occupy an entire pinna of Asplenium platyneuron ( Fig. 170 ). On the larger pinnae of Pellaea , a narrow, gradually widening, serpentine beginning is sometimes evident ( Fig. 169 ). Frass is often not evident on Asplenium spp., but on Pellaea the scattered black grains are conspicuous.

Puparium. Brown; formed within the mine.

Distribution. USA: IL, *IA, *MO, NY, *NC, *OK, TN ( Scheffer et al. 2007). We have found leaf mines on Asplenium pinnatifidum and A. platyneuron in OH and on A. rhizophyllum in VT.
