It may be challenging to determine which beetles are the biggest since there are more than 350,000 recognized species of beetles on the earth, and more are always found. Because of their tenacity and the fact that they nearly never go extinct, beetles are one of the most varied groups of insects. This is mainly because beetles virtually never become extinct. Lets look at the top 10 biggest species of beetles in the world, each of which has a diverse set of traits and a specific habitat.
Wallace’s long-horned beetle
Even if its body isnt very huge or thick, Wallaces long-horn beetle is nonetheless the species of beetle that holds the record for being the longest in the world! These remarkable beetles may grow to be as large as an incredible 26.5 millimeters (10.5 inches) in length, and they are indigenous to the regions of New Guinea, Indonesia, and portions of Australia.
Their enormous antennae, which are generally more than twice as long as the length of the insects body, are responsible for most of their overall size.
Another bug that lives up to its name is the Hercules beetle. The beetle species has the record for its most incredible lifespan and is one of the biggest flying insects in the world. Only the males of this species of rhinoceros beetle have the enormous horns for which the species is named; females of this species do not have horns. It is very uncommon for Hercules beetles to reach a length of up to 7 inches, and this measurement considers the distinctive horn size on their thorax.
Hercules beetles are not nearly as dangerous as they seem; their primary diet consists of decaying and new wood and a wide variety of fruits. Most of the time, rather than hunting prey, they use their horns as a method of self-defense or to battle with other males of the species.
Beetle of the Caucasus
The curving distinguishes the giant scarab beetles, three-pronged horns that protrude from their cephalothorax in the shape of a W. These horns give the beetles their common name. The males often use these horns to compete with one another for mates and food. There are four different subspecies of Caucasus beetles, the majority of which are distributed in the countries of Malaysia and Indonesia. Male Caucasus beetles may grow to lengths of 3.5 to 5 inches or more, making them one of the biggest beetle species in all of Asia.
Within the Goliaths genus, there are six distinct species of Goliath beetles and a significant number of other, less well-known subspecies. Female Goliath beetles typically grow to a length of between 2 and 3 inches, while their male counterparts may grow to a height of up to 4 inches.
As larvae, they may weigh up to 3.5 ounces, equivalent to 100 grams; however, by the time they reach their adult weight, they have often lost quite an amount of weight. Even though they dont have teeth, the mandibles of Goliath beetles are very sharp and may readily pierce the skin and draw blood. They are also extraordinarily powerful insects, with the ability to lift things that are up to 850 times heavier than themselves.
Giraffe stag beetle
Commonly reaching up to 12 centimeters, or 4.7 inches, in length, the giraffe stag beetle is the biggest member of the family of stag beetles found anywhere in the world. These dangerous beetles have mandibles that stand out from others because of the notches and serrations that resemble teeth.
These mandibles account for about half of the whole length of the insects body! Males of this species, like males of many other species on this list, have much bigger mandibles, which they use like antlers to pick each other up and fling each other while battling for food and mates. Males of this species also have a much higher reproductive rate.
Although it is estimated that there are over 1,500 different kinds of rhinoceros beetles, the elephant beetle is one of the biggest of them all.
They may reach a length of anything from 2.25 to 4.75 inches throughout the course of their lives, with the males being noticeably bigger than the females.
Because the male elephant beetles have long, strong horns that resemble trunks, they are known by this name. Elephant beetles battle with other males while fighting for food or mates.
European stag beetle
However, despite their menacing appearance, the mandibles of male European stag beetles are entirely harmless. Even though there are more than 1,200 different species of stag beetles, the European stag beetle is perhaps the most well-known due to its large size and conspicuous pincer-like mandibles. As with the vast majority of other sexually dimorphic beetle species, men have far more giant mandibles than females. The size of a typical European stag beetle might vary significantly according to the country in which it is found.
