Crab Spiders Certain crab spiders exploit Ultra violet light to make themselves "invisible" or disguise themselves from their victims whilst at the same time create a contrast difference to attract their prey to UV absorbing flowers.
These crab spiders reflect UV light strongly against a UV absorbing flower. It has been found that this is not simply by chance but a strategy used by these minute spiders to attract prey.
Through human eyes we can not see this remarkable camouflage strategy as the white crab spiders appear to stand out in marked contrast to the brightly colored flowers on which they hunt. In some cases prey will fly directly towards the open arms of the spider spelling their doom. This amazing camouflage is almost akin to a "cloaking device" as far as their insect prey's vision is concerned.
Enjoy!
