Most butterflies sport colourful, eye-catching wings. But some species flit about using mostly transparent wings. Researchers have now uncovered the tricks that one of these — the glasswing butterfly (Greta oto) — uses to hide in plain sight. The tricks of their transparency include sparse, spindly scales and a waxy coated membrane. Many thousands of insect species are threatened by large-scale deforestation for agriculture and especially pesticides. Help them to survive and #BoycottPesticides #BoycottPalmOil!
