Don’t Touch These If You See Them on Your Plants: Meet the Mourning Cloak Butterfly Eggs That Look Like Alien Art
If you spot clusters of tiny, geometric shapes on your plants this spring, resist the urge to touch them. These are the eggs of the Mourning Cloak butterfly (Nymphalis antiopa), and they resemble something straight out of a science fiction movie.
What Are Mourning Cloak Butterfly Eggs?
Mourning Cloak butterflies are among the first to emerge in spring, often before many flowers bloom. They lay their eggs in distinctive, circular clusters on the twigs of host plants like willows, elms, and poplars. Each egg is encased in a tiny sac with seven white ridges, arranged in a star-like pattern. Initially, the eggs are amber-yellow or pale olive-green, but as they mature, they darken to a near-black hue just before hatching.
Why Should You Avoid Touching Them?
While these eggs may look like alien art, they are a crucial part of the butterfly’s life cycle. Disturbing or removing them can harm the developing larvae and disrupt the natural process. Additionally, the eggs are often laid in areas that are difficult to reach, so touching them may inadvertently cause damage to the host plant.
