Description
Beckers and co-authors studied, in a 2024 report, how female katydids in two lands judge male songs. A song and the taste for it have to match, or mating fails. Yet song systems do change over time. The tropical katydid Neoconocephalus triops lets females weigh beat rate and song form.
Females came from Puerto Rico and Costa Rica. Puerto Rican females were picky about beat rate at both test temperatures and lax about song form. Costa Rican females were picky at the cooler test, lax at the warmer one, and favored songs broken into verses. Loose taste in one trait may let songs drift and split over time. The contrast shows how song systems can start to part.
