Today about a butterfly Gonepteryx cleopatra or Cleopatra, short "Cleo". So here it is in its multispectral representation, resting on a Rudbeckia hirta flower. I took some shots in normal human vision VIS, in UV using the Baader-U (eff. 375nm) and my Jupiter-U (eff. 365nm) and Saturn-U (eff. 325nm) filter, as well as in simulated bee and butterly vision using my XBV2 and XBV3 filters respectively.
I'm presenting all of them in diptych form, VIS image (left) vs filtered image (right)

Quite interesting how that butterfly appears is different spectral representations. Obviously that spot as well as its UV bright rim around its wings is made to attract, which I made visible using my differential method (right):
As you may have noticed, I'm still working on my bee and butterfly vision (BV) filters. More about these special filters here later and in a seperate entry.
Stay tuned, more will follow on that fascinating subject...
