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.
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.
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.
Notorious for skeletonizing leaves of a wide variety of edible and ornamental plants, Japanese beetles have iridescent copper wings and a metallic-green thorax and head. Underneath they have small tufts of white hairs along the sides of their abdomens. The slightly curved, lawn-damaging larvae, also known as grubs, are gray-white with brown heads.

Named appropriately, flea beetles are tiny green or black beetles that jump like common fleas. They attack a wide range of plants, including fruits, vegetables and ornamentals. Adult flea beetles create pinholes in leaves. Read more about controlling flea beetles.
Distinctive 1/2-inch-long yellow insects, Colorado potato beetles feature black, brown and yellow stripes on their wing covers. They gobble up and skeletonize the foliage on plants in the nightshade family, including potatoes, eggplant, peppers and tomatoes. Female beetles lay clusters of bright yellow-orange eggs on the undersides of the leaves. Hump-backed larvae hatch from these eggs and molt several times during feeding, growing fatter each time.

Few garden pests match the destructive power of Japanese beetles. In their mature form, they decimate gardens, leaving skeletonized leaves and weakened plants behind. In their immature stage, when they're commonly called grubs, they feast on tender grassroots, leaving brown, dying lawns in their wake. Controlling these invasive pests requires action during both stages. Understanding where Japanese beetles came from and where they're headed can help you take back the upper hand.
