Costa Rica beetle sports gold color and new study is finding out why
By the University of Exeter press staff

The secrets of why Central American jewel scarab beetles look like they are made from pure gold, has been uncovered by physicists at the University of Exeter.

The ornate beetles, which have a brilliant metallic gold color, are highly valued by collectors. But until now the reasons behind their golden iridescent hue, have not been fully understood.

University of Exeter physicists specializing in color and light have done experiments exploring the origin of the scarab beetles’ striking metallic golden appearance, showing that the golden beetles have a unique optical signature.

The structure of the beetle and its armor uniquely manipulates the way the light is reflected so that it looks like pure gold.

Their results are published in the Journal of the Royal Society Interface.

Pete Vukusic, a physicist specializing in light and color, led the research which involved experiments and advanced modeling.

He found that the golden appearance is due to the high reflectiveness of the beetles’ exoskeleton, which also manipulates a property of the light called its polarization: the orientation of the reflected light wave’s oscillations.

The scientists mapped the optical signature of the beetle’s Chrysina resplendens’ color, and found it was unusually optically-ambidextrous, meaning that it reflects both left-handed and right-handed circularly polarized light.

Vukusic said: “The brilliant golden color and distinctive polarized reflection from the scarab beetle Chrysina resplendens sets it completely apart from the hundreds of thousands of other beautiful and brightly colored animals and plants across the natural world. Its exoskeleton has a bright, golden appearance that reflects both right-handed and left-handed circularly-polarized light simultaneously.

This characteristic of Chrysina resplendens appears to be an exceptional and wonderfully specialized characteristic in currently known animals and plants. It will serve as a valuable platform from which bio-inspired optical technologies can spring.”

The golden jewel beetle is prized by collectors because of its resemblance to the precious metal.

Other scarab beetles, valued by ancient cultures such as the Egyptians for use as amulets which were sometimes wrapped in the bandages of mummies, are jewel-like green and blue colors.

The vast majority of brightly colored beetles tend to be green and do not reflect polarized light. These beetles, in comparison to the brilliant golden color of Chrysina resplendens, lack much more specialized aspects of their exoskeleton’s finely detailed structure.

Ewan Finlayson, research fellow on the project, said: “We were drawn to the study of this jewel scarab not only by its striking metallic golden appearance, but also by its ability to control a less obvious property of the reflected light: the polarization. We have learned that there is great subtlety and detail to be found in these optical ‘signatures’ and in the elaborate natural structures that generate them.”

The golden jewel scarab beetle Chrysina resplendens, mainly found in the Americas, has evolved an exoskeleton that contains intricate nano-structures that are responsible for its appearance.

The spacing of the repeating layers of the nano-structures is found to vary over a specific range through the exoskeleton; a key property that causes the simultaneous reflection of a range of visible colors. It is this fact that explains the very bright reflection as well as the golden hue.

The nano-structured exoskeleton is composed of natural materials including chitin and various proteins. In addition to their brilliant reflectiveness, these structures are remarkable in the way they manipulate the way polarized light is reflected. Their nanostructures produce circularly-polarized light, where the orientation of the light's oscillations rotate as the light travels. The two possible directions of rotation are referred to as left handed and right handed.

The experiments build on the work of an early American scientist called Michelson who, in 1911, looked at the polarized reflection from many different Chrysina beetles, and on the work of Anthony Neville in 1971, who began looking more closely at Chrysina resplendens.

There are around 100 species of Chrysina jewel scarab, which are found exclusively in the New World, mostly in México and Central America.

The species Chrysina resplendens is found in Panamá and Costa Rica. Chrysina scarabs typically live in mountain forests. The larvae feed on rotting logs of various tree species, while the adults feed on foliage. The larval form lasts for several months to a year, and pupation takes a month or two.

After the adult emerges it lives for about a further three months, although this span probably varies between species.
