Epiblema discretivanum (Heinrich)
Eucosma discretivana
âmostly on groundsel-tree, Baccharis halimifolia L., but I reared adults also from narrow leaved groundsel, B. angustifolia Michx. and B. glomeruliflora Pers.â
"Epiblema feed on Compositae; the late instar larvae bore in the stems. The three species treated in this paper produce rudimentary galls."
