So that's How They Do That
Looks like they have figured out how butterflies naveigate. Here's my favorite part
The new study also pinpointed the location of the butterfly's circadian clock, a processor in the brain that governs 24-hour activity and metabolic cycles of insects, humans and other animals. Key genes responsible for the clock's molecular "ticks" were expressed in a brain region called the dorsolateral protocerebrum. In there, tiny neural fibers connect the clock to polarization photoreceptors in the eye.Those must be some instruments they have, It's hard enough to find a butterfly's brain, let alone a small part of it.
