Butterflies Use Antenae (among other things) to Navigate

Researchers used black enamel paint to block Monarch butterflies use of their antennae. The result: those with antennae covered (ore removed) got lost traveling to Mexico from the U.S. (Those with clear paint on their antennae did fine.) The conclusion is that the butterflies use antennae as both light sensors and clocks that work in conjunction with clocks in their brains.
