Insect egg photos

These amazing photos are of insect eggs that were taken with an electron microscope and rendered to reflect their true coloring. Actual eggs range in size from 0.7-2 mm.

Image 1: This is the egg of the Julia heliconian butterfly. It lays its eggs on the tendril of the Pasiflora (or passion flower) plant.

Image 2: The Morpho peleides (blue morpho butterfly) laid this egg. The blue morpho is one of the largest butterflies in the world, with a wingspan of 5-8 inches.

Image 3: The egg of Caligo memmon (the owl butterfly). See that tiny hole at the top? That is where the sperm enters the egg.
