Watch a glasswing passing (without flying colours)

Glasswing butterflies1 (e.g. certain Pteronymia spp.) have large clear patches on their wings.

Many would claim they ‘evolved’ transparent wings (to minimize their visibility to predators). Christians might retort that only a Creator could have made these beautiful see-through wings. Who’s right?

Actually the ‘glass’ wing areas are missing a feature of coloured butterfly wings—scales. Both glasswings and colourful butterflies have transparent wing membranes, but colourful butterflies have pigmented or translucent scales covering them. In iridescent butterflies, by diffracting the light rays in a complex manner, the translucent scales (not pigments) produce the vivid colours, more vibrant than any painting.2 The electron microscope reveals ‘how complex the structures are and difficult to fabricate’.3

Such complexity, which man with all his technology struggles to copy, was surely constructed by Someone even more intelligent (Romans 1:20).

So, colourful (and especially iridescent) butterflies reflect more strongly the Creator’s handiwork than do glasswings. In this post-Fall ‘bondage to decay’ (Romans 8:19–22), glasswings have evidently lost genetic information (for scales)—in common with other observed mutations.

Such mutations demonstrate ‘devolution’, not evolution.4 Natural selection sometimes favours defects—e.g. the glasswing is likely less visible to predators than are colourful butterflies. But this is not evolution—no new information has been produced, notwithstanding that Pteronymia has been given its own genus name, separate from other (coloured) types of Nymphalid butterflies.5

And the fact that the glasswing can fly, just like butterflies with scales,6 confounds evolutionists on two counts. First, the aerodynamic intricacies of butterfly flight defy evolutionary explanation, pointing instead to a Creator.6 Second, the glasswing ‘proves scales are not needed for flight’,7 indicating that the original colourful butterflies were ‘over-engineered’ for flight.8

So why did the Creator bother to make colourful butterflies?

Maybe it’s because God appreciates beauty, and, given that we’re made in His image, He knew that we would, too.
