![]() Goliath beetles, the largest beetles on the planet, have a combination of black, brown and white coloration – they are described in more detail in the section on Brown Beetles below. A type of rhinoceros beetle, the Hercules Beetle is known for its tremendous strength, hence the name. The longest living beetle in the world, as well as one of the largest flying insects, is the Hercules Beetle ( Dynastes Hercules). Some black beetles, such as the stag beetle, were traditionally used as amulets in Italy and other parts of Europe. Orange-black, zebra, brown-black and yellow-black are common color combinations. Bottom line – many black pigmentations occurs in conjunction with other colors. Can Beetles Be Black?īlack pigmentation in beetles create black patches or bands on other backgrounds or predominantly black backgrounds with other colors. In the examples below, some dominant colors have been referred to, including both iridescent and natural pigmentation. The US has over 25,000 species.īeetles are often difficult to classify in terms of color, since they typically sport different shades and iridescence in different parts of their body and elytra. Wings are often a different color altogether.īeetles are the most widespread species on Earth, constituting almost 40% of all insects with over 40,000 known species belonging to the order Coleoptera. In conjunction with the base below, which could be an entirely different color, beetles will often show shimmery, metallic colors based on the angle(s) at which light hits their back. But the angle at which light hits the body will cause the structural colors to change – a shimmering effect we call iridescence.Īs mentioned, beetles usually have multiple layers of scales, with plate-like layers slanted in different directions. Natural pigmentation stays the same whenever or wherever you see it, though many beetles have multi-layered stacks on top of their underlying elytra and inner wings. On the other hand, beetles can show bright blue, green, red, purple, pink or grey/white colors due to structural colors created by photonic cells in their outer shell that reflect certain bands of light in specific ways. There are two types of colors found on beetles:įor example, colors such as orange, brown, black, yellow, as well as certain shades of red or, come from actual pigments in a beetle’s hard shell (called an elytra). ![]() The general consensus is that the colors on beetles serve the purposes of either camouflage or warning to predators. This is different from species like butterflies and dragonflies. Why do beetles flash bright colors? Scientists do not feel that beetles use bright colors to either attract or identify others of the species – they typically use chemical attractions to attract mates. Beatles are everywhere, and they can shine in glorious patches of color! For example, farmers love beetles since they are known to destroy aphid colonies.Įither way, one thing is clear. Depending on your viewpoint, beetles are either pests or they protect our gardens and orchards from invasive species that can destroy our plants.
