Insects can interfere with exercise.
For example, these light-colored objects on the dark bark of a mesquite caught my eye and I had to run home and grab my camera.
Do you recognize it?
Here, look closer.
It’s the exoskeleton shed by a cicada turning from a nymph into an adult. Can you see the covering where the eyes were? How about the large front legs used for digging?
The bulbous area in front of the eyes is the covering for the part of the mouth that pumps fluids from plants. The flap-like structure on the side of the body is the wing bud that develops into the wing of the adult.
Have you ever found a cicada nymph exoskeleton? Where did you find it? Did you look at it closely?
I used to collect exoskeletons like these when I was a kid. So fascinating!
They are. You can even see the linings of the air tubes inside.
