Largest Insects in the World
Largest Insects in the World
Insects, which are a type of arthropod, are easily the most numerous group of multicellular organisms on the planet, with about a million species identified so far. The title of heaviest insect in the world has many rivals, the most frequently crowned of which is the larval stage of the goliath beetle, Goliathus goliatus, the top size of which is at least 115 g (4.1 oz) and 11.5 cm (4.5 in). The largest confirmed weight of an adult insect is 71 g (2.5 oz) for a giant weta, Deinacrida heteracantha,[1] although it is likely one of the elephant beetles, Megasoma elephas and Megasoma actaeon, or goliath beetles, both of which can commonly exceed 50 g (1.8 oz) and 10 cm (3.9 in), can reach a higher weight.[1] .The Goliath beetles (named after the biblical giant Goliath) are any of the five species in the genus Goliathus. Goliath beetles are among the largest insects on Earth, if measured in terms of size, bulk and weight.[1][2] They are members of subfamily Cetoniinae, within the family Scarabaeidae.[1] 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. Goliath beetles measure from 60–110 millimetres (2.4–4.3 in) for males and 50–80 millimetres (2.0–3.1 in) for females, as adults, and can reach weights of up to 80–100 grams (2.8–3.5 oz) in the larval stage, though the adults are only about half this weight. The females range from a dark brown to silky white, but the males are normally brown/white/black or black/white.[1].The titan beetle is one of the largest beetles, with the largest reliable measured specimen being 16.7 cm (6.6 in) in length,[1] comparable to such beetles as Xixuthrus heros (15 cm (5.9 in)) and the Hercules beetle, Dynastes hercules, in which giant males occasionally can grow up to 17.5 cm (6.9 in),[2] but the Hercules beetle males have an enormous horn on the pronotum or thorax making up around half of its total length.Attacus atlas, the Atlas moth, is a large saturniid moth endemic to the forests of Asia. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
Contents.Giant weta are several species of weta in the genus Deinacrida of the family Anostostomatidae. Giant weta are endemic to New Zealand and are examples of island gigantism.
There are eleven species of giant weta[1], most of which are larger than other weta, despite the latter also being large by insect standards. Large species can be up to 10 cm (4 in), not inclusive of legs and antennae, with body mass usually no more than 35 g. One captive female reached a mass of about 70 g (2.5 oz.), making it one of the heaviest documented insects in the world[2] and heavier than a sparrow.Phryganistria is a genus of stick insects belonging to the subfamily Clitumninae. It was described by the Swedish entomologist Carl Stål in 1875. Members of the genus are found only in Southeast Asia.
