Some stick insects even sway gently to mimic the movement of branches in the wind. Their mimicry is so convincing that they can go unnoticed by both predators and observers, making them fascinating subjects for naturalists.
Firefly
(Lampyridae spp.)
Fireflies are enchanting insects commonly found in the Cuyabeno Reserve, especially during the warm, humid nights.

Termites
(Isoptera spp.)
Termites are social insects, playing a vital role in the ecosystem as decomposers. Known for their wood-eating habits, these small creatures are essential for breaking down cellulose found in dead trees and plant material, returning valuable nutrients to the soil. They have a unique mutualistic relationship with protozoa in their guts, which help them digest cellulose, allowing them to thrive on a diet that many other animals cannot utilize. Termites live in large colonies, which can consist of thousands or even millions of individuals, working together to build intricate tunnels and nests.
