The largest of the earwigs is the Saint Helena earwig (Labidura herculeana), which is up to 8.4 cm (3.3 in) in length. There are no recent records of this species and it is generally considered extinct. [12] The largest certainly living species is the Australian giant earwig (Titanolabis colossea), which is about 5 cm (2.0 in) long. [7]
The titan beetle (Titanus giganteus) is a Neotropical longhorn beetle, the sole species in the genus Titanus, and one of the largest known beetles, as well as one of the largest known insects, at over 170 mm (6.7 in) in length. Adult titan beetles only live for a few weeks, and protect themselves from predators with their sharp spines and ...
Most species are at least 2 cm (0.8 in) long, although smaller species, down to 0.9 cm (0.35 in), also exist. The largest are members of the genus Lethocerus, which can exceed 12 cm (4.5 in) and nearly reach the length of some of the largest beetles in the world. [1] [3] [4] Giant water bugs are a popular food in parts of Asia. [5]
Goliath beetles can be found in many of Africa's tropical forests, [1] where they feed primarily on tree sap and fruit. [ 1 ] [ 2 ] Little appears to be known of the larval cycle in the wild, but in captivity, Goliathus beetles have been successfully reared from egg to adult using protein-rich foods, such as commercial cat and dog food.
Amblycheila hoversoni, also known as the South Texas giant tiger beetle, is a flightless and nocturnal tiger beetle species found in south and west-central Texas, United States. First described in 1990, it is the largest tiger beetle species in the Western Hemisphere .
Prosopocoilus giraffa, the giraffe stag beetle, is the world's largest stag beetle [1] and is a member of the family Lucanidae within the order Coleoptera. They have very long, toothed and notched mandibles that protrude about half the size of their body. They tend to be aggressive and are fierce and powerful.
To get the two male beetles to lock in combat, a female beetle is used, or a small noisemaker duplicating the female's mating call. Entomologist Séverin Tchibozo suggests the larvae contain much more protein (40%) than chicken (20%) and beef (approximately 18%), and they could become a protein source for a large human population .
The beetles are the largest order of organisms on earth, with about 400,000 species so far identified. The most massive species are the Goliathus , Megasoma and Titanus beetles already mentioned. Another fairly large species is the Hercules beetle ( Dynastes hercules ) of the neotropic rainforest with a maximum overall length of at least 19 cm ...
