You always know where to find me, right? In my yard. I’m a big gardener. Seeing your hard work come to fruition and witnessing your plants grow is a deeply satisfying experience. Let’s face it, though – it can be very difficult. Bug control is one of the main obstacles. Sometimes you’re not even sure which pests are good for you and which ones would destroy all your hard-earned possessions.
I just saw a photo floating around social media that encapsulates this uncertainty. It scared me when I first saw it. The image shows a leaf covered in extremely small, highly detailed black geometric patterns. At first, it looked like the leaf was wrapped in an alien grid, or perhaps some strange disease. Like me, many others were curious about what it could be.
I looked into it and discovered that these strange patterns are actually the eggs of Nymphalis Antiopa butterflies. Let me introduce this species to you if you are not familiar with it. The Mourning Cloak butterfly, Nymphalis Antiopa, is an intriguing insect with an unusual life cycle and some intriguing characteristics.
Let’s start by discussing the eggs. These eggs on a leaf were visible in a close-up in the photo I saw. They resemble a thin layer of fine black lace that has been applied to the surface. Once you get over your initial shock, it’s actually quite beautiful. Clusters of eggs are laid, and each little egg is a marvel of impeccable geometry. “This is either going to be really good for my garden or really bad,” was my initial thought when I saw it.
Fortunately, there is good news: the Nymphalis Antiopa butterfly has several uses. Although the caterpillars or larvae eat leaves, they usually prefer willows, elms and poplars among other trees and shrubs. So you should be safe if you have a garden that is full of vegetables and flowers. Since these butterflies also feed on decaying fruit and help with the decomposition process, they can actually be quite useful.
It’s fascinating to watch these butterflies go through their entire life cycle. The caterpillars emerge from these strange, complex eggs after they hatch. Their bodies are bristly and spiked and are black with tiny white dots. They go through a series of stages called instars, during which they grow and shed their skin.
When they reach adulthood, the caterpillars find a safe place to pupate. They transform into a pupa that looks like a small sleeping bag. Depending on the environment and the time of year, this stage can last a few weeks or a few months. When they emerge, they are stunning mourning-cloaked butterflies, with dark, velvety wings, speckled with blue and surrounded by a bright yellow border.
