Cactophagus circumdatus is a striking neotropical snout beetle. Belonging to the family of true weevils (Curculionidae), this wood-boring weevil is instantly recognizable by its long, prominent snout, known as a rostrum. At the very tip of this rostrum are specialized chewing mouthparts, which the beetle uses to bore into tough plant tissue. While the genus name implies a diet of cacti, many tropical members of this group have adapted to specialize in feeding on lush rainforest understory plants like wild aroids. In fact, true weevils owe their staggering evolutionary success to this precise combination of strict specialization and incredible adaptability. I encountered this beautiful weevil in the protected forest of “La Perla”—a precious sanctuary that remains from the vast rainforests that covered the coast of Ecuador in ancient times.
