Croesus lydius, a spectacular member of the Birdwing family of butterflies. Here, the butterfly is posed to show the underneath of the orange and black wings. 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 top of the wings showing. You will not believe the difference between the top and bottom of the wings. Can you imagine watching this spectacle of nature flapping its wings?
