More into priamus caelestis I would say, or urvillianus, as aesacus has different pattern.

Right. it's just on my monitor it looked more turquoise than the dark blue of urvillianus

I use plain tap water on birdwings. I've seen brown staining, but as has been mentioned, it disappears when the wings dry. The blue color changes, though, are permanent. That's strange - when I've had brown staining it's been permanent. I always assumed that it was fat leaching out of the body rather than "darkening" caused by water...  Simon |

It as been my experience that using hot water injection to soften Ornithoptera leads to permanent brown staining where the wings meet the body. Perhaps, the heat causes permanent staining.Humidity softening using tap water can cause brown staining, but I have found that a acetone bath can usually remove this. I no longer use water-
I use Gin or Vodka soaked in paper towels to soften my specimens. Since it has a lower vapor point, I find that it effectively softens the butterflies and dries them out faster to set condition. Moreover, the alcohol content eliminates any susceptibility of mold growth.

Yes, injecting must be done carefully with Ornithoptera. These stains won't get away.
