Giant Walkingstick
Megaphasma denticrusAlso known as Texas Giant Walkingstick
Reaching lengths of over seven inches, giant walkingsticks rank among the longest insects native to North America. These master impersonators spend daylight hours motionless along twigs in oak and mesquite woodlands, swaying gently to mimic branches in the wind. At night, they climb actively into canopy foliage to feed on leaves, relying on their slender form and bark-like colors to evade hungry birds.

Responsible observation
- Flashlight Spotting: Scan oak and mesquite branches after dark with a soft flashlight to find active individuals.
- Observation Etiquette: Avoid grabbing males directly by the hind legs to prevent getting pinched by their thighs.
- Wind Motion: Watch for their distinct rocking movement, which mimics a twig blowing in a gentle breeze.
