Croesus lydius, a spectacular member of the Birdwing family of butterflies. The combination of orange, black, and yellow is stunning. Alfred Wallace, upon discovering this butterfly wrote in 1869 that seeing it caused his "heart to beat violently…and I felt much more like fainting that I have done when in apprehension of immediate death." An absolute beauty. We also sell this butterfly framed with the underneath showing. You will not believe the difference between the top and bottom of the wings. You also will be amazed by how exquisitely beautiful the underneath of the wings are.
