Recently, while listening to the cicadas buzzing in the trees, my husband has remarked to me that he loves their sound. This was surprising to me because I had always thought of the sound as being the sound of the heat of the sun (as a small, ignorant child) and it corresponds to that drowsy feeling of the dog days of Summer. His love for their sound has sparked for me a curiosity regarding cicadas, their habits, and how they even make such a unique sound.
I looked up cicadas and how they make that sound. Apparently they have tymbals on their sides which function in conjunction with the other parts of the cicada's body to act as a mini speaker. They are capable of making sounds up to about 110 decibels (if I remember correctly), and are considered to be one of the loudest of all insects.
My husband showed me recently an app called Google Scientist which lets you tap into all the sensors on your phone to measure things such as decibels and much more. Shouting into my phone as loud as I thought proper for indoors and with neighbors outside, I measured my own voice at a maximum of about 75-80 decibels. Basically, those cicadas are singing louder than I was willing to shout (without hurting my voice).
My curiosity has been quite happily satisfied, then, to have been able to observe a couple of young cicadas hatching out of their nymph skins with their brand new wings. Those wings are a beautiful kind of teal color before they're dried. I've never seen such a thing before! It was quite fascinating.
I must admit, on a field trip yesterday I was quite pleased to allow the six kids in my group to hold the cicadas we found in a short nature walk. We were looking for as many bugs or birds, or whatever we could find (within a very short fifteen minutes) as we were able. We spotted a couple of dragonflies, bees, cicadas, cabbage butterflies, ants, but we were most fascinated by the slow, clumsy, and totally harmless cicadas. My coworkers were sincerely repulsed to discover the kids holding and carrying old cicada skins and the hatched adults in their hands. As much as many find this kind of activity repulsing, it hearkens back to my own childhood playing in dirt, leaves, sticks, and more. In this kind of play there were no rules, the imagination was key, and the possibilities were endless.
As for the two brothers who catch endless insects, I further discovered that their mom encourages this type of thing as her field of study in college was related to conservation and the environment.
