This is not a tasty gummy sweet but a Jewel Caterpillar (family Dalceridae) found in Amazon Rainforest. They are covered with sticky goo-like, gellatinous tubercles that provides protection from its predator like ants until they metamorphosise into winged moths.

Terrifying Volcanic Lightning Photographed
Photographer Martin Rietze recently traveled to Japan where he had the incredible opportunity (or near grave misfortune?) of photographing the Sakurajima Valcano in southern Kyushu as it spewed forth smoke, fire, and lava bombs.
If that wasn’t enough the hellish volcano also caused a lightning show that lasted over 20 seconds giving the photographer ample time to
flee for his lifetake these stunning photographs. You can see many more images from the series right here. Of note, the photographer’s grit and fearlessness landed the top photo a feature on NASA’s Astronomy Picture of the Day earlier this week.
Early birds may have flown on four wings
Two-winged flight followed emergence of avian ancestors.

Instead of two wings, the first birds might have used four feathered limbs to stay aloft, according to research published today in Science.
Birdlike dinosaurs, such as Microraptor and Sinornithosaurus, are known to have had long, sturdy feathers on their hindlimbs. But until now, researchers were not sure whether the earliest birds had already abandoned this extra plumage when they emerged to take to the Cretaceous skies over 100 million years ago.
The researchers, led by Xing Xu, a palaeontologist at the Institute of Geology and Paleontology in Shandong, China, found evidence of feathers on the hindlimbs of 11 basal bird specimens (gathered from the Lower Cretaceous Jehol Group in China). On some of the individuals, these feathers appeared to be veined flight feathers that stood perpendicular to the leg bones, similar to those in the basal bird Archaeopteryx.
One specimen, attributed to the Sapeornis genus, had at least one hindlimb feather longer than 50 mm. Feathers on the feet were shorter, but were still more than 30 mm long…
