Blue Is the Most Popular Color in the World

If you were to ask a group (just about any group) of people to name their favorite color, more than any other color they would reply "blue." Of course, after seeing some of the spiders in this article, that reply might change, but that is doubtful. The color blue is also considered the most beautiful when it comes to eyes. Blue eyes, blue skies, blue oceans, blue birds and blue flowers...we love them all.

But, blue pigments are rare in nature and Mother Nature has always had a way of favoring green, brown and other duller colors. With this article, we have set out to showcase some creatures for which she has chosen the most popular color in the world.

Blue Spiders Are a Mystery to Scientists

After reading several scientific journals and reports, it's safe to say that scientists still haven't presented a definitive reason as to why some spiders are blue. According to a study reported at www.sciencemag.org, the glowing blue - a color rarely found in animal pigments - is a structural color.

But, a recent study reported by www.thesun.co.uk suggested that it may have something to do with their evolution pattern.

If you just can't get enough of blue spiders in your life, this poster is available online - thanks, but I'm going to pass.

Blue Cloud Forest Millipede

It's important to remember that just because something is beautiful, there's no need to touch - this beauty's toxic secretions are deadly.  This is the blue cloud forest millipede (Pararhachistes potosinus) and it is the largest millipede on earth.

The Electric Blue Day Gecko

The electric blue gecko, which is found mainly in eastern Tanzania.  These shy creatures are tiny (usually about two to two and a half inches long), but have a lifespan of up to 10 years.  They love sunshine!

The Blue Iguana

The critically-endangered blue iguana is found in the wild only on the Grand Caymen Island in the Caribbean, where they are considered emblematic creatures.

The Blue Dragonfly

There's no need to be afraid of this beautiful blue dragonfly.  He won't sting or bite, but can fly up to about 30 miles per hour, so if you blink you may miss him.  Check for these guys around water.

You may never get to see a blue dragonfly up close, but macro nature photographers  continue to keep us entertained and informed.

Blue Poison Dart Frogs

These frogs (in any color) are considered one of Earth's most toxic, or poisonous, species, each with enough poison to kill thousands of mice. The color is a notification for potential predators to stay away. Scientists pretty much agree that these frogs get their toxicity from the insects they slurp up with their long, sticky tongues. Some of the insects they like to dine on include small beetles, ants, fruit flies, termites, and crickets. Poison dart frogs can be found in the rainforests of Central and South America.

A Blue Mud Dauber and a Blue Flower Wasp

The blue flower wasp (Discolia soror) is also sometimes called the black flower wasp or hairy flower wasp.  They are most commonly found in Australia, where they are very much appreciated by gardeners.
