The spectacular Ulysses butterflies (Papilio ulysses) pass through our garden quite frequently but rarely stop to rest or feed. With a wingspan of just over 100mm they are as big as the Orchard Swallowtail and bigger than any of our other butterflies apart from the Cairns Birdwing. Their flight is fast and erratic and the brilliant iridescent blue flash of their upper wings is irresistible.
But they hide it when they rest, obviously to avoid predators’ attention. The best chance of photographing the upper wings comes when they hover as they feed. As the writer at Wild Wings & Swampy Things, a blog about wildlife in the Daintree region north of Cairns, says, “Flashes of their brilliant blue amongst the flowers are hard to capture but it’s fun trying!”
The results of a basic image search, however, are overwhelmingly of wings-open specimens. How? I think people cheat or, if that’s too harsh, stage their photos: butterflies lethargic with cold, or dead specimens, are put in position for a studio shot; or existing images are combined in Photoshop. That’s not to deny the occasional lucky shot of a hovering butterfly, of course, but just to say that the photographs don’t honestly reflect the reality. The same is true, although to a lesser extent, of images of our Cairns Birdwing, which is equally paranoid about showing its gaudy upper wings in real life but flashes them at all and sundry in photos.
