Entimus Imperialis
''Entimus imperialis'', common name Brazilian diamond beetle, is a species of broad-nosed weevils belonging to the family Curculionidae, true weevil and the Entiminae subfamily. Description ''Entimus imperialis'' can reach a length of about . The basic colour is black. Elytra are strongly convex and laterally compressed, punctured with longitudinal rows of golden-green dots, filled with scales composed by crystals of chitin and resembling little diamonds (hence the common name). Diamond beetles are also used for ladies' jewelry. The scales of ''Entimus imperialis'' appears iridescent (i.e., exhibit colour changes with viewing angle) because of the presence of three-dimensional photonic crystals.

Johann Reinhold Forster
Johann Reinhold Forster (22 October 1729 – 9 December 1798) was a German Continental Reformed church, Reformed (Calvinist) pastor and natural history, naturalist of partially Scottish descent who made contributions to the early ornithology of Europe and North America. He is best known as the naturalist on James Cook's Second voyage of James Cook, second Pacific voyage, where he was accompanied by his son Georg Forster. These expeditions promoted the career of Johann Reinhold Forster and the findings became the bedrock of colonial professionalism and helped set the stage for the future development of anthropology and ethnology. They also laid the framework for general concern about the impact that alteration of the physical environment for European economic expansion would have on exotic societies. Biography Forster's family originated in the Lord Forrester, Lords Forrester in Scotland from where his great-grandfather had emigrated after losing most of his property during the ...

Curculionidae
The Curculionidae are a family of weevils, commonly called snout beetles or true weevils. They are one of the largest animal families, with 6,800 genera and 83,000 species described worldwide. They are the sister group to the family Brentidae. They include the bark beetles as the subfamily Scolytinae, which are modified in shape in accordance with their wood-boring lifestyle. They do not much resemble other weevils, so they were traditionally considered a distinct family, Scolytidae. The family also includes the ambrosia beetles, of which the present-day subfamily Platypodinae was formerly considered the distinct family Platypodidae. Description Adult Curculionidae can be recognised by the well-developed, downwards-curved snout (rostrum) possessed by many species, though the rostrum is sometimes short (e.g. Entiminae). They have elbowed antennae that end in clubs, and the first antennal segment often fits into a groove in the side of the rostrum. The body tends to be robus ...

Entiminae
The Entiminae are a large subfamily in the weevil family Curculionidae, containing most of the short-nosed weevils, including such genera as ''Entimus'', ''Otiorhynchus'', ''Phyllobius'', ''Sitona'', and '' Pachyrrhynchus''. In comparison with their stunning diversity, only a few of these weevils are notorious pests of major economic importance. Entimines are commonly encountered in the field, including urban environments, and abundant in entomological collections. Diversity There are over 12000 described species worldwide, distributed in over 1370 genera, nearly 14000 by more recent counts. Most tribes are represented in only one biogeographic region of the world. The current classification within the subfamily has been recognized as artificial rather than reflecting natural groups. General morphology Besides the shape of their broad and short rostrum, most entimines are easily recognized by the presence of a mandibular scar that appears when a deciduous process falls of ...

Photonic Crystal
A photonic crystal is an optical nanostructure in which the refractive index changes periodically. This affects the propagation of light in the same way that the structure of Crystal structure, natural crystals gives rise to X-ray crystallography, X-ray diffraction and that the atomic lattices (crystal structure) of semiconductors affect their conductivity of electrons. Photonic crystals occur in nature in the form of structural coloration and animal reflectors, and, as artificially produced, promise to be useful in a range of applications. Photonic crystals can be fabricated for one, two, or three dimensions. One-dimensional photonic crystals can be made of thin film layers deposited on each other. Two-dimensional ones can be made by photolithography, or by drilling holes in a suitable substrate. Fabrication methods for three-dimensional ones include drilling under different angles, stacking multiple 2-D layers on top of each other, direct laser writing, or, for example, instig ...

Beetles Described In 1771
Beetles are insects that form the Taxonomic rank, order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, Elytron, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungus, fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.
