Close-ups of butterfly wing scales! You should definitely click on these images to get the full detail.

I’ve paired each amazing close-up (by macro photographer Linden Gledhill) with an image of the corresponding butterfly or moth.  The featured lepidoptera* are (in order of appearance):

*Lepidoptera (the scientific order that includes moths and butterflies) means “scaly wing.” The scales get their color not from pigment - but from microscopic structures that manipulate light.

The great science youtube channel “Smarter Every Day” has two videos on this very subject that I highly recommend:

Happy April Fool’s Day!

We challenge you to plan out the most epic prank this April Fool’s. If you’re running low on ideas, check out the Prankster Skill for more projects like this head in a jar illusion. Using a photo editor, blend two images together to create a flat image of a head, laminate it, and submerge it in a jar.  When the flattened image is inserted into the curved jar, the water distorts it - giving it the illusion of a decapitated head in a jar of preserving fluid.

Have fun!
