Beetles come in various sizes

Beetles range in size from extremely small species to truly giant species. The shortest beetle species is the feathered beetle (family Ptiliidae), most of which are less than 1 mm in size. On the other hand, the giant beetle (Goliathus goliathus) can weigh up to 100 grams. The longest known beetle comes from South America and is called Titanus giganteus, which can grow to over 30 centimeters in length.

The giant beetle, despite its terrifying size, is completely harmless to humans. This insect hides in the tropical jungles of South America and only crawls out when looking for a mate. It is surprising that the larvae of this creature have never been seen, however, scientists believe that the larvae can be more than 5cm in diameter and up to 30cm in length.
