Hypolimnas bolina: the Great Eggfly ๐ฆ
Some butterflies wear their colours like jewels, and the Great Eggfly is a perfect example.
Found across tropical and subtropical regions of the Indo-Pacific, Hypolimnas bolina is known for the striking white spots set against deep brown-black wings, often surrounded by iridescent blue and violet hues.
But there is more to this butterfly than its beautiful appearance.
One of its most fascinating features is sexual dimorphism: males and females can look remarkably different. Males display bold, contrasting patterns, while females are highly variable, often mimicking other butterfly species that are distasteful to predators.
Even more remarkable is the species' reproductive biology. In some populations, a bacterium called Wolbachia can selectively affect male embryos, resulting in a strongly female-biased sex ratio.
A beautiful reminder that butterfly evolution is shaped not only by flowers, predators and climate, but also by the invisible world of microorganisms.
Nature's details are often more extraordinary than they first appear.
