Our photo of the day comes from the rainforest of Ecuador. The natural world's knack for camouflage is undeniably cool, but see-through creatures take it to the next level. It's really quite profound – how to evade predators? Become invisible. Known as protective transparency, there are some 1,200 types of glasswing insects alone – the planthopper above, photographed by Andreas Kay in Ecuador, is just one of many.
