In insects, tympanal organs play an important role in behaviors such as communication, defense, sexual selection, site selection, protection, and communication with each other and with the environment. Tympanal organs are usually identified by the presence of a tympanal membrane. The aim of this article is to give information about the structure of the abdominal ear organs in Pyralidae. In the study, the tympanal structures of 4 species belonging to the subfamilies Pyralinae and Phycitinae were examined comparatively. Diagnostic features of the studied ear organs of Synaphe consecratalis (Pyralinae), Pyralis regalis (Pyralinae), Dioryctria sylvestrella (Phycitinae) and Pempelia alpigenella (Phycitinae) are given.
