Watch butterflies float through the air in slow-motion. The beloved butterfly delights with its colorful wings and light touch. But there are some surprising facts about this insect. For starters, the butterfly has a dramatic personal history considering that, during metamorphosis, a caterpillar must digest its own body before transforming into a butterfly. Butterflies taste with their feet. Sensors on the back of their legs determine the quality of sugar in a flower. Before depositing eggs, a female butterfly uses her feet to taste whether a leaf would be edible to future caterpillars. A butterfly's wing scales can detach to help it escape from spider webs or other dangers.A few butterflies, like the Zebra Longwing, are equipped with microscopic hearing organs that can detect sound. Its two eardrums are located at the base of the underside of its wings. Along with their wings, butterflies use body posture to adjust their direction and momentum in the air. These butterflies were filmed in macro, slow-motion, and thermal imaging. Thanks to the Natural History Museum of Los Angeles for opening the door to their Butterfly Pavilion.
