Batrachedrodes sophroniella is a moth of the Batrachedridae family. It is endemic to Oahu, Maui and Hawaii. The larvae feed at times abundantly on the sporangia of Dryopteris cyatheoides. The larvae feed protected by a web. When there are no more sporangia, they feed on the undersurface of the frond, eating away the parenchyma and leaving the upper epidermis which then shows as dead spots. Pupation takes place within a cocoon alongside of the midrib of a pinna.
