Deep in the Amazon forest, you will indeed find many large beetles. However, Titan beetles will catch your attention. The Titan beetle is the biggest insect in the beetle family3, with a body length of up to 6.5 inches.
The Titan is so big that they may be unable to take off from the ground. It will need to launch its wings from a tree to gain momentum.
Interestingly, scientists have not observed the Titan beetle larvae. However, based on the sizes of boreholes in trees, their larvae are also quite long. Titans also have huge mandibles and strong jaws. These mandibles can rip into human flesh. When threatened, this beetle makes a hissing sound to defend itself.
While the Titan beetle is the largest beetle, it is not the largest insect in the world.
Stick insects, also known as leaf insects or ghost insects, are some of the largest insects in the world, consisting of about 3,000 species. They are also some of the longest ones in the order Phasmatodea.
The longest stick insect belongs to the genus Phobaeticus, including the species Phobaeticus serratipes and Phobaeticus chani, each with a body length of up to 21 in.
However, the world’s longest insect record belongs to a newly discovered species called the Phryganistria chinensis. This stick insect has a body length measuring 25 in. It was found and bred at the Insect Museum of West China.
This big insect has a flat tubular appearance resembling a stick. It can easily hide from predators by blending into branches and leaves. The stick insect can play dead on tree branches to defend itself until the predator loses interest. It may even lose a leg to escape predators and regenerate it later.
The next on our list of giant insects in the world is the Atlas moth. You can find Atlas moths located all over Asia. This insect is so big that it is considered one of the largest species of moths2.
However, only the White Witch moth and the Hercules moth have a longer wingspan than the Atlas moth. The Hercules moth is the largest moth in the world. The Atlas moth has a wingspan that falls between 249 to 250 mm in females and from 210 to 230 mm in males.
The moth has beautiful snake-like patterns on its wings, which help it protect itself from predators. Also, at the larval stage, the Atlas moth releases a secretion to help guard against predators like ants, lizards, and birds.
Tarantula hawks are the largest wasps in the world. These large species can measure up to 2 inches long. These wasps are formidable predators capable of hunting down tarantula spiders, a food source for their larvae. The female tarantula hawk lays its eggs in the spider’s abdomen, and when these eggs hatch, they eat the spider alive.
What’s notable about the Tarantula hawk is their massive stingers. These stinging wasps have some of the most painful insect stings in the world. The pain from the tarantula hawk species Pepsis grossa sting is second only to the bullet ant.

Known for its massive horns, the Hercules beetle is one of the longest species of beetles on our planet1. You will only find these longhorns in male Hercules beetles, which they use to fight other males when looking for a mate.
This horn also accounts for more than half of the male Hercules beetle, bringing them to a length of up to 7 inches. You can find Hercules beetles in Central and South America rainforests and the Caribbean islands.
In the remote regions of Papua New Guinea, you will find the butterfly species called Queen Alexandra’s Birdwing. This beautiful butterfly is also the largest in the world. It is so rare that a single specimen could cost thousands of dollars.
Regarding their body and wingspan, the females have a slightly larger body and wingspan than the males. The female's body can measure up to 3 inches with a wingspan of over 10 inches.
Sadly, the Queen Alexandra’s Birdwing falls under an endangered species due to habitat destruction.
The Actaeon beetle is one of the biggest insects in the beetle world. It belongs to the family Scarabaeidae and is a rhinoceros beetle. This beetle is named after a famous Theban hunter in Greek mythology.
Its body measures about 50 to 120mm, and its dorsal surfaces are matte or shiny black. It has large tarsal claws and powerful legs. You will notice appendages resembling horns on the head of the male beetles. The females lay eggs, which take around nine months to develop.
The Actaeon beetle is also one of the heaviest insects. In 2009, experts found the heaviest Actaeon, weighing 228 grams in the northern regions of South America, nearly the same as a female rat.
Elephant beetles do not have a trunk or look like elephants, but these beetles are one of the largest insects on the earth. While they do not have trunks, the male species have horns, which they use to show dominance, competing for food and mates. The males are also bigger than the females. But these beetles can grow up to 5.11 in.
They are black but have yellowish hair, making them yellowish-black. You can find these creatures in tropical environments in parts of Mexico and South and Central America. Elephant beetles are herbivores and feed on sap and tree bark.
The Chinese mantis is a praying mantis species native to China and other parts of Asia. It has a long, slender body appearing in brown and green colors. It is longer than most praying mantises and grows between 2.75 and 4 in long.
The Chinese mantis is a carnivore and can tackle and eat large insects, including grasshoppers, crickets, cockroaches, moths, and spiders.

The giant leopard moth (Hypercompe scribonia) is a moth of the family Erebidae. They are distributed through North America from southern Ontario, and southern and eastern United States through New England, Mexico, and south to Colombia.[2][3] The obsolete name, Ecpantheria scribonia, is still occasionally encountered.
Giant clams, standing as the largest bivalve molluscs, make their homes in the coral reefs in the Tropical Indo-Pacific region.
The record holder for size was over 4.5 feet long. Discovered in Indonesia in the early 19th century, its estimated weight was around 550 pounds when alive3.
In terms of behavior, these marine mollusks are stationary. They respond to disturbance by retracting their vibrant mantle tissue and closing their shells.
Like most bivalves, they are filter feeders. However, the zooxanthellae, a unicellular algae living symbiotically within the clam, provide most of its nourishment.
Without the ability to move, these hermaphrodites release sperm and eggs into the water, allowing nature to take its course.
The Giant Moray Eel lives in the Indo-Pacific region's rocky seafloors and coral reefs. It is the world's largest moray eel, measuring 10 feet and weighing over 66 pounds. (The Slender Giant Moray Eel is longer.) Its brown skin has a unique dark spot pattern contrasting with the colorful reefs.
Moreover, this nocturnal eel hides in crevices and caves to avoid predators and rest for its nighttime hunts for fish, cephalopods, and crustaceans.
The Giant Moray Eel also forms alliances with coral groupers to hunt prey. It chases prey into open waters while the grouper takes advantage.
The New Caledonian Giant Gecko is the largest gecko species on the planet, with adults reaching up to 17 inches in length. These types of geckos have robust bodies and large heads, with unique granular skin covering them.
Their color palette ranges from greens to browns, often decorated with patterns of varying shades, enabling them to blend into tree bark and foliage.
This type of gecko is a nocturnal predator that feeds on insects, fruits, and small mammals, occasionally indulging in cannibalism.
They also communicate through growling, barking, and hissing, which are crucial, especially during the mating season.
The Indian Giant Squirrel inhabits India's rainforests. It is one of the largest squirrels in the world, with a body length ranging from 25 to 45 cm and a tail that can grow up to 60 cm.
The squirrel's coat is a mix of chestnut, maroon, black, and white, and its big, round eyes help it see in the dense forests where it lives.
Indian Giant Squirrels live alone, high up in trees, constructing large, globe-like nests from twigs and leaves.
They eat fruits, flowers, nuts, tree bark, insects, and bird eggs and play an essential role in spreading seeds and helping new plants grow.
Besides their impressive size and colorful appearance, Indian Giant Squirrels are skilled acrobats. They hang upside down from branches, stretching their bodies to reach their food.
The Black Giant Squirrel has a striking black coat contrasted by cream to cinnamon hues on its underparts. Their body can grow up to 15 inches while their tails can be twice as long.
It's an arboreal animal found in Southeast Asia's mature forests that feeds on seeds, nuts, fruits, leaves, insects, bird eggs, and young birds.
Like oriental giant squirrels, this squirrel rarely ventures to the ground, preferring the trees' safety, where it communicates with its fellow squirrels through distinct calls.
The giant Chinese salamander is a critically endangered salamander species. It is the world’s largest amphibian. Chinese salamanders have an average length of 1 meter and weigh 11 kg. Their bodies are heavily built and flat, with short but sturdy limbs.
They can live for up to 60 years. The conservation status of giant Chinese salamanders is critically endangered. Researchers could only find 24 giant Chinese salamanders in the wild. Excessive hunting by humans caused an alarming decline in their population.
The Giant Otters or Giant River Otters are the largest otter species in the world, standing tall at 5.5 feet, including the tail, and weighing 70 pounds.
These social creatures live in the rivers and streams of South America. These diurnal carnivores mainly eat fish, but they also eat crabs, snakes, and small caimans.
Additionally, the Giant Otter is the most vocal among otter species. A study discovered 22 unique vocalizations among adults and 11 in baby otters3.
