Cicada Brood XIX Molting

Periodical Cicada- Brood XIX

I went for a walk around 9am today. I headed for the Shiloh greenway and was welcomed by the sound of the periodical cicadas! I posted about my first sighting earlier this week.

I headed for the older trees to look for cicadas. I found a bunch of discarded shells on the trees, leaves and ground.

Shell with tracheal tubes

Did you know that those white strings are the cicada’s tracheal (breathing) tubes?

I changed directions to look at a different set of trees. Boy, was I in for a treat! A cicada was in the process of molting right at eye level! I took a bunch of pictures as the nymph freed itself from its shell, unfolded its wings, grew darker, and finally climbed away from the empty shell.

Below is a series of pictures taken over two days. They are two different nymphs, covering the entire molting process.

The back begins to split
A larger break
The head begins to emerge
The back breaks free
The head and wings are out
More of the body is pulled out
Starting to stretch its wings
Some legs are free
The nymph is perpendicular to the shell
More legs wiggle free
Bending toward the tree
Pulling out the rest of its body
The body is completely out
The wings begin to unfold
Wings unfolding
Wings elongated
Wings are complete
Wings rest at the side of the body
The head and body begin to turn gray
The head and body continue to darken
The adult cicada walks away from the shell
Climbing higher up the tree
The adult cicada

Isn’t that fascinating?

As the nymph was molting, an adult cicada came by to check out the action.

One other thing I learned about cicadas this week: they pee. Apparently, they will spray all over you if you’re in the right spot at the right time. Yesterday, I caught a picture of this one with a few drops coming out of it. It won’t hurt you, but consider yourself warned!

Cicadas spray!

Have you seen or heard the periodical cicadas yet? Let me know!
