This chapter discusses the results of the first ultrastructural investigation of the sensilla of mayfly Ephemera danica using Scanning and Transmission Electron Microscopy (SEM, TEM). The findings reveal that the flagellar sensilla are mainly located on the dorsal side of the flagellum, and are represented by long trichoid sensilla and shorter basiconic sensilla. The results also suggest that the long trichoid sensilla serve as mechanoreceptors, while the shorter basiconic senilla perform a chemo-mechanical function. The chapter also discusses the presence of these sensilla in relation to the behavioral ecology of this burrowing insect.

Keywords:   sensilla, Ephemera danica, SEM, TEM, flagellum, mechanoreceptors, chemo-mechanical function, behavioral ecology
