Bottom Attack

Katydids are fascinating insects that might be more commonly heard than seen. They send out a rhythmic hum on warm summer evenings and are excellent at blending into the tree leaves and foliage around them. These large, bright-green insects lay eggs at summer’s end and don’t survive the winter. Their unique physical characteristics, including long antennae and leaf-like wings, help them adapt to their environment and distinguish them from their relatives, such as grasshoppers and crickets. Once topside, the nymphs climb up into the trees where they proceed to plant themselves on a branch and transform into winged adults by once again shedding their exoskeletons. 

Cicadas have a fascinating life cycle that involves shedding their exoskeletons, or “skins,” as they transition from nymphs to winged adults. Here’s how it works:

Nymph Stage: cicadas have a fascinating life cycle that involves shedding their exoskeletons, or “skins,” as they transition from nymphs to winged adults. Here’s how it works:

Cicadas spend most of their lives underground as nymphs.

After 17 years (in the case of the 17-year cicadas), they dig tunnels to the surface using their front legs, creating little mounds of mud known as “cicada huts.”

When the ground temperature reaches around 64 degrees Fahrenheit (18 degrees Celsius), the nymphs emerge from their tunnels and climb onto nearby trees.

Once on the tree, the nymphs shed their old exoskeletons. These discarded shells, called exuviae, are perfect replicas of the nymphal cicadas. You might even notice little white strands coming out of these shells.

After shedding their skins, the nymphs transform into winged adults.

Male cicadas serenade females with their loud calls, leading to mating and egg-laying.

Once the eggs hatch, the nymphs return underground to feed on tree roots, continuing the cycle.

When I was a little girl the cicadas came one summer. We called them katydids but they were cicadas.

I was entranced with the exoskeletons they left fastened to the trees. They split right down the back and back out. Then the adults fly away. 

I went all over the street unfastening them from the trees and 'saving' them in my back pocket. Of course they were crushed back there.

One day I had been busy collecting the shells as I called them. My parents were outside chuckling about my collection.

Suddenly I began to jump up and down. I screamed. I ran for my mommy!

Something was attacking my bottom! It hurt.

I had plucked a katydid from a tree before it left its skin. It was trying to claw its way out of my back pocket. It needed to finish its mission.

Sadly that was the end of my collecting of exoskeletons.
