 They often follow courting pairs of the closely related species "T. antoniae".When those pairs lay eggs, "T. sarasinorum" darts in and eats the eggs.On four different occasions in the field (out of 136 observation bouts in total), a male "T. sarasinorum" who was following a pair of courting "T. antoniae" eventually chased off the male "T. antoniae" and took his place, courting the heterospecific female.
