Paper Wasp (Polistes aterrimus) 🐝 These incredible insects build their nests from a mix of wood fibers and saliva—creating a paper-like structure that gives them their name. Costa Rica is home to many species of paper wasps, each playing an important role in the ecosystem. Here at Arenal Observatory Lodge & Trails, every encounter reminds us how nature’s tiniest architects shape the rainforest 😍 | Arenal Observatory Lodge & Trails
