I spotted this super-cute little leaf beetle (family: Chrysomelidae) during a trip to Yasuni National Park, a stunning protected area of the Amazon rainforest in Ecuador. It belongs to the Eumolpinae subfamily, a massive group of over 7,000 species known for their brilliant, metallic iridescence. As gorgeous as they are on camera, they’re actually notorious troublemakers for farmers; the larvae target roots while the adults strip the leaves of crops like citrus, palms, and sweet potatoes. Because there is so much diversity within this group, trying to identify the exact species from a photo alone is a massive challenge
