The Rainbow Stag Beetle (Phalacrognathus muelleri): Nature's Living Jewel
The rainbow stag beetle, Phalacrognathus muelleri, is a biological marvel renowned for its iridescent metallic hues that rival precious gems. Native to the forests of Australia and New Guinea, this coleopteran species has captivated entomologists and pet enthusiasts alike with its structural coloration—a phenomenon produced by microscopic wing surface ridges that refract light into a spectrum of blues, purples, golds, and greens.
