Butterflies and Moths


Did you know...
the wings of butterflies and moths are actually transparent?

The iridescent scales, which overlap like shingles on a roof, give the wings the colors that we see. Contrary to popular belief, many butterflies can be held gently by the wings without harming the butterfly. Of course, some are more fragile than others, and are easily damaged if not handled very gently.

Did you know...
butterflies taste with their feet?

Their taste sensors are located in the feet, and by standing on their food, they can taste it!

All butterflies have six legs and feet. In some species such as the monarch, the front pair of legs remains tucked up under the body most of the time, and are difficult to see.

Did you know...
butterflies don't have mouths that allow them to bite or chew?

They, along with most moths have a long straw like structure called a proboscis which they use to drink nectar and juices, used much like the straw that comes with your soft drinks from McDonald's. When not in use, the proboscis remains coiled like a garden hose.

Some moths, like the Luna moth doesn't have a proboscis. Their adult lifespan is so very short they do not eat at all. They simply seek a mate, reproduce, then die.


The Asian Vampire moth pierces the skin with its strong, sharp proboscis and drinks the blood of animals. So there really are vampires, just not the kind we see in movies, humans!

Did you know...
the butterfly doesn't spin a cocoon?

You will often erroneously hear and read that the adult butterfly emerges from its cocoon. Moths spin cocoons of silken threads, often using leaves to help surround themselves.

Caterpillars shed their final skin to reveal a pupa. The outer skin of this pupa hardens to form a chrysalis which protects and hides the amazing transformation that is occurring inside.

Pupae take on a wide variety of appearances, depending on the species of butterfly. Some hang from beneath leaves or twigs. Others are girdled to the side of a stem much like a worker on a telephone pole. Some are smooth and shiny while others are rough and even spiky. Some are beautifully colored with dots and lines of gold while others are drab and barely noticeable. No matter what the design, the function is the same - to lessen the chances of being eaten by a predator and to increase the likelihood of producing an adult butterfly or moth.

Did you know...
most butterflies fly during the day, and most moths fly during the night.The best way to identify a butterfly from a moth is to look at its antenna. A butterfly's antenna have knobs at the ends of their feelers, and the ends of the moth's antenna is either feather like or plain. Most butterflies rest with their wings held up above their bodies and most moths rest with their wings spread out flat. Typically butterflies have brightly colored wings and moths have dull colored wings. Most butterflies have slender, hairless bodies, while most moths have a fat abdomen and furry bodies. Most moths have tiny hook or bristle hooking the forewings and hind wings together. Butterflies do not have this hook. Moths have existed about 100 million years longer than butterflies. So although butterflies and moths appear very much alike, there are quite a number of differences.

Rainbows


Did you know...
It doesn't have to rain for us to see a rainbow it can be seen in the early morning dew, in the fine mist from a waterfall or in the spray of water from the ocean. But it must be from some sort of water as the rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky (or other places) when the Sun shines onto droplets of moisture in the Earth's atmosphere. They take the form of a multicolored arc, with red on the outer part of the arch and violet on the inner section of the arch. A rainbow spans a continuous spectrum of colors; the discrete bands are an artifact of human color vision. The most commonly cited and remembered sequence, in English, is Newton's sevenfold red, orange, yellow, green, blue, indigo and violet (popularly memorized by mnemonics like Roy G. Biv or (R)un O)n Y)ou G)reat B)ig I)vy V)ine

Contrary to popular belief, the light at the back of the raindrop does not undergo total internal reflection, and some light does emerge from the back. However, light coming out the back of the raindrop does not create a rainbow between the observer and the sun because spectra emitted from the back of the raindrop do not have a maximum of intensity, as the other visible rainbows do, and thus the colors blend together rather than forming a rainbow.
