When wandering around in the jungle, you should be looking for big things like trees but you also need to keep your eyes open for some of the very small things. Cicadas have been a part of my life as long as I can remember. They are described as follows:
The cicadas (/sɪˈkɑːdə/ or /sɪˈkeɪdə/) are a superfamily, the Cicadoidea, of insects in the order Hemiptera (true bugs). They are in the suborder Auchenorrhyncha,[a] along with smaller jumping bugs such as leafhoppers and froghoppers. It is divided into the Tettigarctidae, with two species in Australia, and Cicadidae, with more than 1,300 species describedfrom around the world; many undescribed species remain. See Wikipedia: CicadaCicadas spend most of their life underground as nymphs and emerge only every 13 to 17 years when they emerge, usually in large numbers, and shed their skins and become flying adults. Where I lived in Arizona, they would show up in huge numbers on the trees and bushes.
I found this cicada skin on a leaf while hiking on a jungle trail in Costa Rica.
