  • Nature is filled with colors and it is generous with all creatures and life forms, including the insects.
  • Amongst the Beetles, there are various sub-species that are quiet dazzling and colorful.
  • These insects use their colors to hide from predators and blend into the surrounding.
  • They are also hard to find as they mostly live far away from areas inhabited by humans.

Nature is filled with colorful creatures, and beetles are no exception. Usually when we think of beetles, the image that comes to mind is the common black insect that we see everywhere. However, beetles have adapted to their environments in unique ways, with their colors being part of the adaptation process, with scarab species being popular examples. Although beetles with bright colors are some of the prettiest bugs you’ll see, these colors and patterns help them fool predators or blend in with their surroundings.

The most beautiful beetles come from a variety of habitats. You might not have heard of some of these beetle species, but you’ll enjoy learning more about them. Here is some more details about how these insects made our list.

The Tiger Beetle (Cicindelinae) is a land beetle, rather than being one of the flying species. Adult beetles have iridescent shells that help these inch-long insects stand out. Although the bodies are somewhat conspicuous, making the bugs easily as noticeable as scarabs, they boast powerful jaws that allow them to defend themselves from predators. These colorful beetles have shells in bright shades of green, with some blue highlights. Habitat destruction has given these insects Endangered IUCC status, making a thriving population a sign of minimal local habitat loss.

These beetles are a part of the jeweled scarab group, which includes some of the most fascinating beetles in the animal kingdom. Similar beetles to this species have shells in silver tones. Like others among the most beautiful beetles, these bugs fool predators because their shells shine so much in the light.

The Blister Beetle is a flying beetle that commonly has a striking, deep orange shell color accentuated with black stripes. Green and yellow are also popular marking colors. These beetles, native to North America, have the Least Concern status because of a built-in defense mechanism. The species can secrete a toxic oil from its joints when facing a predator threat, an effective deterrent. This oil secretion is a perfect compensation for the brightly-colored shell, which attracts some predators not as easily deterred when seeing the colors. Some predatory species cannot see the colors of these colorful beetles indicating toxicity, making the insects easy prey in such circumstances.

Atlas Beetle: An Impressive Size to Go With Impressive Colors
