| Blue and mauve color
swallowtail butterflies make a gorgeous display
in the black frame with powder-blue
matting in the picture below. The large blue emperor
butterfly, also known as papilio ulysses is a beautiful
species, from Indonesia, that has a wingspan reaching
almost 4 inches from wingtip to wingtip. The males
are brighter with iridescent blue-green colors
in strong contrast to their black ground wing colorations.
The females are more subdued, but both sexes have
black tails and irregularly scalloped hindwings.
