Morse of a different color

Some of the prettiest sights of summer are the swarms of fireflies that come out at night. In some parts of the world, their yellow, blue, and magenta lights are so bright that it's possible to read by them!

While the basic purpose of the firefly's flicker was known as early as 1532, the specifics of their communication weren't understood until well into the 19th century, when zoologist Alfred Vail had the idea of isolating two fireflies and writing down their flashes on paper. When he finally broke the code in 1829, he showed it to his friend Samuel Morse who, in a fit of Franklin-esque chicanery, stole it and took credit for its invention.

Morse, it turns out, had recently designed the first telegraph, and had been searching for a language for communicating messages with his new machine. This new "Morse code" fit the bill perfectly.

And as so often happens in history, Morse became a millionaire off of his stolen ideas, while Vail, the original inventor, died in debtors' prison.

Smug as a Bug in a Rug

The critically endangered Tunisian parrot beetle (Leptinotarsa psittacus) is the only species of insect capable of imitating human speech. It uses this talent to scare off predators, which universally fear humans.

The beetle's extra-precise antennae can pick up sound waves from up to ten yards away or more. After picking up a suitable sound, it spins a cocoon where it will hibernate for three weeks, processing the audio data. Once it has emerged from its cocoon, it can use the tymbals on its hind legs to reproduce the sound.

But here's the crazy part: the parrot beetle can only play back a sound once! After that, it must begin the recording and processing steps all over again. A single parrot beetle can use more than 500 sounds in its lifetime!
