Category: Family Fun Dates: Thursday, 03 April 2014 to Sunday, 14 September 2014 Celebrate the beauty of the butterfly at the Natural History Museum this spring, as the prestigious venue erects the tent on its front lawn that is kept warm and humid for these incredible creatures. The attraction returns for its sixth consecutive year, allowing visitors to come face to face with such stunning specimens as the swallowtail, blue morpho, the moon moth and many others - originating from far flung locations including Africa, Southeast Asia and North and South America. All the more incredible than the sight of thousands of these insects in one place is watching them hatch from the chrysalises - a natural life cycle that you can see here. Observe as the newborn butterfly frees itself, delicately batting its wings until dry, and then taking flight. Here at The Chesterfield Mayfair, we take it upon ourselves to preserve populations of insects. This is why we keep bees in our lofts, and the guests benefit from the honey they produce. Make the most of the warmer months with our special Mayfair Summer package.
