Summary:
- Researchers utilized fossilized specimens of *Archaboilus musicus*—a Jurassic-era katydid—to reconstruct its ancient mating calls through biomechanical modeling of its wing structures.
- By analyzing the physical spacing of the insect's stridulatory organs (the file and scraper), scientists were able to determine the specific frequency and acoustic properties of the sound produced 165 million years ago.
- This study offers a rare auditory window into prehistoric ecosystems, revealing that these insects occupied a specific acoustic niche that likely influenced the evolution of hearing in other contemporary species.
