[4] [5] The second-largest member of the genus likely is Phryganistria heusii yentuensis, with a total length of up to 52 centimetres (20 in) and a body length up to 32 centimetres (13 in). [ 2 ] [ 6 ] Another, Phryganistria tamdaoensis was selected in 2015 by the International Institute for Species Exploration as one of the "Top 10 New Species ...
The largest is the dobsonfly Acanthacorydalis fruhstorferi, which can have a wingspan of up to 21.6 cm (8.5 in), making it the largest aquatic insect in the world by this measurement. [38] This species is native to China and Vietnam, and its body can be up to 10.5 cm (4.1 in) long. [39]
It is the world's longest stick insect, which also makes it the world's longest insect. A wild collected female kept at the Insect Museum of West China in Chengdu was the record holder at 62.4 centimetres (24.6 in) in total length (including extended legs) and 36.1 centimetres (14.2 in) in body length, [ 1 ] [ 2 ] but it was surpassed by one of ...
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]
The genus belongs to the Meganeuridae, a family including other similarly giant dragonfly-like insects ranging from the Late Carboniferous to Middle Permian. With single wing length reaching 32 centimetres (13 in) [1] and a wingspan about 65–75 cm (2.13–2.46 ft), [2] [3] [4] M. monyi is one of the largest-known flying insect species.
Species in this genus are 4 to 9.7 cm (1.6–3.8 in) long and can have a wingspan of up to 20 cm (8 in); the world's largest cockroach by length and wingspan is M. longipennis. [1] [2] [3] Megaloblatta, like many other insects, use stridulation in order to steer their predators away. [4]

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.
