Giant Katydid
Stilpnochlora coulonianaAlso known as Florida Giant Katydid, Cuban Giant Katydid
Giant katydids spend their lives perched high in subtropical tree canopies, blending seamlessly into foliage with broad, leaf-veined forewings. Males produce quiet, high-pitched acoustic clicks to court females, who respond with subtle answering taps rather than the loud choruses typical of smaller katydids. After mating, females lay overlapping, scale-like rows of flat oval eggs cemented along tree twigs.

Responsible observation
- Spotting by Night: Scan dense tree crowns and garden shrubbery after dusk with a flashlight to detect reflective eye-shine.
- Porch Light Encounters: Check outdoor wall fixtures in warm months, where dispersing adults are often drawn to bright lights.
- Gentle Handling: Allow an individual to walk onto an open hand rather than gripping its delicate, leaf-like wings.
