  • We all know that beautiful, elegant caterpillars build chrysalises and turn into hideous, nightmarish

  • butterflies. But what happens inside a chrysalis? What creates those little abominations?

  • Here’s what doesn’t happen: caterpillars slowly morph into butterflies, growing wings,

  • eyes, etc in the process.

  • Nope! It’s actually a lot grosser than that:

  • A caterpillar’s own digestive juices dissolve its body, turning it into a soup of proteins

  • with some random body parts thrown in.

  • Aww, caterpillar soup...just like my aunt Sheila used to make!

  • Anyway, that soup also includes cells calledimaginal discswhich grow into butterfly

  • structures like wings while the body re-forms. Bake at 375 on the bottom rack for a few more

  • minutes, and voila, a butterfly!

  • The craziest part is that in spite of turning into goop and back again, butterflies can

  • retain memories from their caterpillar days. Which means that somehow, some nerve connections

  • survive that change. The scientific conclusion here is: don’t be a jerk to a caterpillar,

  • or itll hate you forever as a butterfly. Like tiny things that might hate you?

  • Watch my video on viruses. I’m going to play like a second or two of that for you
