This is a picture of five Painted Lady Butterfly eggs on the tail side of a Lincoln Penny under a USB microscope at about 30X magnification. The distance between each pillar is about 0.05 cm or 5 mm, and that is the width of the eggs. The eggs have an eerie luminescent glow with fin like ribs. The coating looks like of cellophane wrapper material. What is amazing is how different they are from birds eggs, in that they are not smooth.
