Epiblema strenuana, the stem-galling moth or ragweed borer, is a moth of the Tortricidae family. It is endemic to North America, but was introduced to Australia from Mexico to control the weeds of the family Asteraceae (Xanthium occidentale, Ambrosia artemisiifolia and Parthenium hysterophorus) in 1982. It is occasionally misspelled as Epiblema strenuanum. The wingspan is about 15 mm.
