''Marmara fraxinicola'' is a moth of the Gracillariidae family. It is known from Québec and the United States (Ohio, Vermont and New York).〔(Global Taxonomic Database of Gracillariidae (Lepidoptera) )〕 There is one generation per year. The larvae feed on ''Fraxinus americana'' and ''Fraxinus pennsylvanica''. They mine in the stem of their host plant. They mine above the ground level in the main stem and branches of the tree. They feed in the periderm, as it does when it occurs in the absence of congeners on white ash. The mine has the form of an extremely long serpentine mine in the twig, mainly on saplings or in rapidly growing shoots. The larva overwinters in the mine, resumes mining, and pupates in the spring in a broadened chamber at the end of the mine. ==References==
