I guess the ants got hold of an insect with beautiful wings, because I found these on the verandah yesterday - On close inspection the structure of them is truly astounding. Nature is almost invariably right about the best and most efficient way to go about things, and finding these reminded me that some fella in the US was working on replicating the structure of dragon-fly wings for use on an LSA-type aircraft. IIRC he had made one set of prototype wings, I think they were about 3-4m span, so about half scale. He made them without molds, by winding strands of glass and carbon fibre around nails in a curved board and then infusing them with epoxy resin. I recall that they were working well on a large model with quite a heavy wing-loading. Although the structure was similar to the insect wings he'd changed the shape to suit powered/gliding flight rather than ornithoptering. The covering, or clear part, was Tedlar or Mylar and the interesting aspect was that the wings were un-strutted and designed to be flexible like a fishing rod. This meant that they didn't need to have a 6+G capability because under load they would flex and 'spill' air, thereby unloading themselves, in a similar way a mono-hull yacht unloads the mast by heeling under a sudden gust. I haven't seen anything about it since then, and can't find anything on the net at the moment other than for use as flapping robotic drones - I last saw it about 4-5yrs ago - so I was wondering whether anyone else has kept up with his progress, if any?
