Glasswing Butterfly

Beautiful butterflies with transparent wings. The Glasswing (Greta oto) is a brush-footed butterfly, and is a member of the subfamily Danainae, tribe Ithomiini, subtribe Godyridina. For other glassings (unrelated) see Ornipholidotos. Its wingspan is 2.2 to 2.4 in (5.6 to 6.1 cm).
Adults range from Mexico through Panama. G. morgane oto visits common flowers like lantana, but prefers to lay its eggs on plants of the tropical Solanaceae genus Cestrum. The green caterpillars feed on these toxic plants and are perhaps toxic to predators through secondary chemicals stored in their tissues; caterpillar chemical extracts are unpalatable to Paraponera clavata ants. Adults are also assumed to be toxic, but their toxicity mainly results from males feeding on flowers (e.g., Asteraceae) whose nectar contains pyrrolizidine alkaloids. These same alkaloids also are converted into pheromones by the males and used to attract females. G. oto adults also exhibit a number of interesting behaviors, such as long migrations and lekking among males.
