Beetle Species Study Is Never-Ending

Beetles are essential to life on Earth, serving as food for many animals, but that isn’t all they do. Some beetles recycle carcasses, and others recycle dung. Some beetles help restore the environment after a forest fire. Others exhibit strange and interesting behaviors, such as spraying a noxious chemical at their enemies. One beetle species walks upside-down underwater. Many more beetles do interesting things and fulfill very important roles. Some beetles damage crops or are pests in other ways, especially when they are accidentally moved to new habitats. However, even those beetles that are a nuisance often fill very important roles in their natural environment.

Scientists estimate that there are between five and ten million insect species, which make up about 90% of the world’s animal species. However, only about 925,000 species have been studied enough to be formally described. Of all insect species, the largest number are classified as beetles. Smithsonian sources identify about 350,000 beetle species, but more are discovered each year.

Of the beetle species, about 70,000 are in the Staphylinidae family. One subgroup within that family is Platydracus. According to Wikipedia, there are more than 280 identified Platydracus species. However, recent research in China has identified and recorded 61 previously unknown species. Classifying all beetle species will be an enormous job that will probably never be completed.

We often fail to realize how much diversity exists in the natural world. God has created so many different species, and we haven’t yet been able to study most of them. Even if life has existed on Earth for four billion years, that is not enough time for Darwinian evolution to produce all the species and variety of animals that inhabit this planet.

The more we learn about God’s creation, including the beetle species, the more we are amazed by the complexity and diversity of the essential species that make advanced human life possible.
