![]() Heterospecific pairings also resulted in a high degree of mortality for native males. We demonstrate that native males are more attracted to the chemical cues of introduced females than those of conspecific females. ![]() Miomantis caffra is invasive in New Zealand, where it is widely considered to be displacing the only native mantis species, Orthodera novaezealandiae, and yet mechanisms behind this displacement are unknown. Here, we test the potential for reproductive interference through heterospecific mate attraction and subsequent predation of males by females of a sexually cannibalistic invasive praying mantis. Overlap in the form of sexual signals such as pheromones raises the possibility of reproductive interference by invasive species on similar, yet naive native species. Fatal attraction: sexually cannibalistic invaders attract naive native mantidsįea, Murray P.
