On display behaviour and courtship in the praying mantis Ephestiasula amoena (Bolivar)

Display behaviour in a small species of Indian praying mantis, Ephestiasula amoena , is described and the possible role of this display in courtship is discussed. The display involves exposure of the bright pattern on the inside face of the expanded plate-like profemora. The profemoral patterns found in closely related species are discussed and it is suggested that the display may also play a role in species recognition. The courtship behaviour of E. amoena is contrasted and compared with the courtship of other species of praying mantis.
