The Rainbow Dance Of The Peacock Spider

It’s no secret that many people have a deep seated and, mostly, irrational fear of spiders. They’re the very definition of creepy crawlies with their venomous sacks, furry legs, and beady eyes. I mostly reserve my fear for millipedes but I can sympathize with people who freak out around spiders. Honestly I think spiders get a raw deal. After all, they spend most of their time depopulating our houses and wild-lands of pesky bugs. And their webs are truly architectural marvels of utility and aesthetic design. Really we should be happy to see spiders around; I’d take them over the fleas, ticks, and mosquitoes they hunt any day. Spiders can come in a wide variety of colors but there’s one species that seems like they couldn’t make up their minds.

Peacock Spiders are really a sight to behold. Their beautiful plates shine with bright and vibrant colors that put most of the animal kingdom to shame. The first time I saw one I thought it was a trick of the light. Even knowing better I still have a hard time believing they’re real. Unfortunately not all Peacock Spiders get to be so colorful.

Only the males get to wear these awesome colors. The females go for a more traditional whitish, brownish camouflage.

Even without the coloring they’re still pretty cute though.

The male’s colorful coat is the main focus of their courtship dances. And they say chivalry is dead.

Peacock Spiders have excellent vision and can even see into the ultraviolet light spectrum.

Technically, they belong to a family of jumping spiders known as Salticidae.

The sharp blue in their coats is created by a series of nanostructures that reflect light along specific wavelengths.

The red coloring is created through common pigmentation.

If the female isn’t impressed by his dance she may just decide to eat him. Everyone’s a critic!

  1. Awesome stuff! 🙂
    I love jumpers! I have some in Baltic Amber (as fossils) that are around 50 million years old.
