The Mediterranean katydid (Phaneroptera nana) female sings in response to the male, prompting the male to move towards the female. This is unique to the species, because in other species of katydids, it is usually the female moving towards the male in response to hearing their chirps. However, because the females stay static while the males move to locate them, the females are at less risk of encountering threats and predators. However, the males will not decide to interact with a female unless they illicit a response within 60 milliseconds, ensuring that the female is close enough to them.
The females are selective of the males they respond to, and generally they prefer longer chirps. At least two chirps from the males are needed for the female to entertain the males and reply to them. However, more chirps than that from the males do not make the females more likely to duet with the males.
The female Mediterranean katydids lay their eggs in the lamina of plants. the female does this by bending her abdomen and chewing on the lamina to create an opening. The eggs she lays around 3mm in size on average. Those eggs usually hatch in summertime but that can vary. The timing means that P. nana is usually easily encountered through the summer and fall seasons.
