Hosts. Poaceae  : Agrostis  alba  L.” [= stolonifera L.?], Bromus tectorum  L., Calamagrostis  * canadensis (Michx.) P. Beauv.  , * Cinna arundinacea  L., Elymus  * canadensis L.  , E. glaucus Buckley  , E. repens  (L.) Gould, Hordeum vulgare  L., Pascopyrum smithii (Rydb.) Á. Löve  , Phalaris arundinacea  L., Phleum pratense  L., Setaria pumila (Poir.) Roem. & Schult.  , Triticum aestivum  L., Zea mays  L., Zizania aquatica  L. ( Frick 1959; Spencer 1969). Since Juncus tenuis Willd.  ( Juncaceae  ) would represent a new host family for Cerodontha incisa  , we have chosen not to list it among the confirmed hosts until males can be reared from this plant.

Leaf mine. ( Fig. 131View FIGURES 124–132) A whitish, sometimes inflated, upper surface blotch, with up to four larvae feeding together. Frass is in scattered black grains.

Puparium. ( Fig. 28View FIGURE 22–29) Elongate, black, iridescent; formed within the mine.

Distribution. Widespread in the northern half of the US and in Canada, south at least to OK and NC; Europe; Pakistan; Japan (Nowakowski, 1973).
