The caterpillar of the Brazilian Skipper Butterfly has translucent skin that offers an eerily clear view of its insides, especially the circulatory system.
Brazilian skipper butterflies are larger than most skipper butterflies, but it’s not their size that sets them apart as a species, it’s their appearance during the caterpillar stage. What really makes this tiny critter special is its translucent skin, which offers a very clear view inside the caterpillar, revealing the organs and especially the circulatory system. This see-through skin gives the Brazilian skipper caterpillar a very strange look, especially when you realize that the twitching dark line that runs down its back, from its head to the rear of the abdomen, is the heart.
