Lethocerus indicus is a giant water bug in the family Belostomatidae, native to South and Southeast Asia, as well as southeast China, the Ryukyu Islands, and New Guinea. [1] It was originally described as Belostoma indicum but is no longer placed in that genus.
This insect is well known as an edible species in a number of different Southeast Asian cuisines. The taste of the flight muscles is often compared to sweet scallops or shrimp.
The Asian region has several species of Belostomatidae including L. patruelis , L. insulanus, L. indicus, and Kirkaldyia deyrolli . L. indicus typically has a length between 6.5 and 8 cm (2.6 and 3.1 in). [1] Lethocerus insulanus is found along the islands of Southeast Asia to northern Australia and has a medial dark stripe between the light stripes of the pronotum while patruelis (found from southern Europe to Myanmar) has narrower light stripes and the first tarsomere on the foreleg is longer than the claw (almost equal in L. indicus). Kirkaldyia deyrolli is paler and lacks pronotal stripes. The genus Kirkaldyia can be distinguished from Lethocerus by more widely separated eyes, and the presence of two asymmetrical furrows on the inner setal pad of the fore femur. [2]
The species is distributed widely in peninsular India, Sri Lanka, Bangladesh, into Southeast Asia, extending east to Taiwan and south along Sumatra, Java, Indonesia, Philippines and parts of western Papua New Guinea.
Glands in the abdomen produce odorous chemicals that include (E)-2-hexenyl acetate, (E)-2-hexenyl butanoate, 1-undecen-3-one, 3-mercaptohexyl acetate, and 3-mercapto-1-hexanol which may have a role as an attractant particularly in males. The first two are said to impart a sweet banana-like smell. [3]
The large size of this insect and its flight muscles and the ease of dissection makes it an excellent model organism for muscle structure with special features pertinent to the cardiac muscle. The high degree of structural order makes is possible to obtain X-ray diffraction patterns richer and more detailed than those from vertebrate striated muscle.
The Vietnamese call this insect cà cuống. It is a highly prized food and often boiled and fried whole. The insect's essence (a pheromone produced by the male that attracts females) is harvested by collecting its liquid-producing sacs. That liquid is then placed in small glass containers. The insect is claimed to be scarce,[ citation needed ] and demand for the extract is high. Most of the cà cuống essence on the market is therefore imitation, with the actual essence fetching a high price. Cà cuống is typically used sparsely and eaten with bánh cuốn (rice noodle rolls) by adding a drop to the nước chấm (dipping sauce).
It is also eaten in a soup dish called 'bún thang' adding a unique essence to the broth. The dish traditionally includes rice noodles, thinly sliced egg crepe, pork cold cuts, and other various additions in a chicken/dry squid broth. A tiny drop of the extract on the tip of a toothpick would suffice to flavor the whole bowl of soup. This dish originated in Northern Vietnam.
In the northeast region of Thailand, eating insects is common. In other parts of Thailand, including the Central and Southern regions, the aromatic essence from this species of insect, known as maeng da (Thai : แมงดา), maeng da na (แมงดานา) or maeng da na (แมงดานา), is also popular. The water bug can be eaten whole and fried, and as an extract. [4] Maeng da is used to make nam phrik maeng Da, a type of chili sauce used as a condiment. [5]
In the Ilocos region in the northern part (Luzon) of the Philippines some insects such as crickets, locusts, and beetles are traditionally eaten. The water bug or water beetle is known as alukap in Ilokano language. It is sauteed or fried in oil, garlic, onions and tomatoes, or roasted, after the wings and legs have been removed, and eaten as a viand for steamed rice or as a finger food with liquor. The same is done in the Visayas region where it is called obus in the Visayan language. [6]

Yong tau foo is a Hakka Chinese dish consisting primarily of tofu filled with ground meat mixture or fish paste. Variations on this dish feature - instead of tofu - vegetables and mushrooms stuffed with ground meat or fish paste. Yong tau foo is eaten in numerous ways, either dry with a sauce or served as a soup dish.
Shrimp paste or prawn sauce is a fermented condiment commonly used in Southeast Asian and Coastal Chinese cuisines. It is primarily made from finely crushed shrimp or krill mixed with salt, and then fermented for several weeks. They are either sold in their wet form or are sun-dried and either cut into rectangular blocks or sold in bulk. It is an essential ingredient in many curries, sauces and sambal. Shrimp paste can be found in many meals in Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Vietnam. It is often an ingredient in dip for fish or vegetables.
Belostomatidae is a family of freshwater hemipteran insects known as giant water bugs or colloquially as toe-biters, Indian toe-biters, electric-light bugs, alligator ticks, or alligator fleas. They are the largest insects in the order Hemiptera. There are about 170 species found in freshwater habitats worldwide, with more than 110 in the Neotropics, more than 20 in Africa, almost as many in the Nearctic, and far fewer elsewhere. These predators are typically encountered in freshwater ponds, marshes and slow-flowing streams. 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. Giant water bugs are a popular food in parts of Asia.
Chicken feet are cooked and eaten in many countries. After an outer layer of hard skin is removed, most of the edible tissue on the feet consists of skin and tendons, with no muscle. This gives the feet a distinct gelatinous texture different from the rest of the chicken meat.
Lethocerus deyrollei is a species of giant water bug that traditionally is included in the genus Lethocerus, although recent authorities place it in the monotypic Kirkaldyia. They are large, predatory and nocturnal insects. They are one of the best known giant water bugs and are found in Japan, Korea, east China, east Indochina and the Amur region of Russia. They are very common in much of their range, but have declined drastically in some regions and are considered threatened in Japan and Korea. They live in still waters with vegetation, hatching in the summer months and then overwintering half a year later as adults. They primarily feed on small fish, amphibians and aquatic insects, but have also been recorded taking water snakes and young turtles.
Lethocerus is a genus of the hemipteran family Belostomatidae, known colloquially as giant water bugs, toe biters and electric light bugs, distributed in tropical, subtropical and temperate areas of the world. The greatest diversity of species occurs in the Americas, with only a single species in Europe, two in Africa, two in Australia and three in Asia. It includes the largest true bugs with species capable of reaching a length of over 12 centimetres (4.7 in). The South American L. grandis and L. maximus are the only species to commonly exceed 9 cm (3.5 in), with more typical lengths for the remaining species being between 4.5 and 9 cm. Lethocerus sp. are distinguished from other genera in the Lethocerinae by two symmetrical furrows in the inner pad of setae on the fore femur, the external borders of parasternites II and III narrowed and nearly straight, and with the setae of the tarsomeres following the line of the tibial setae.
Bamboo shoots or bamboo sprouts are the edible shoots of many bamboo species including Bambusa vulgaris and Phyllostachys edulis. They are used as vegetables in numerous Asian dishes and broths. They are sold in various processed shapes and are available in fresh, dried, and canned versions.
Nam phrik is a type of Thai spicy chili sauce typical of Thai cuisine. Usual ingredients for nam phrik type sauces are fresh or dry chilies, garlic, shallots, lime juice and often some kind of fish or shrimp paste. In the traditional way of preparing these sauces, the ingredients are pounded together using a mortar and pestle, with either salt or fish sauce added to taste.
Lethocerus insulanus is a species of giant water bug of the family Belostomatidae. Its common name is the Australian giant water bug, but it is also called the electric light bug or giant fishkiller. These names are also used for various other members of the family, including the other Australian species, L. distinctifemur, which is similar to L. insulanus.
The welfare of farmed insects concerns treatment of insects raised for animal feed, as food or pet food, and other purposes such as honey and silk.
Lethocerus patruelis is a giant water bug in the family Belostomatidae. It is native to southeastern Europe, through Southwest Asia, to Pakistan, India and Burma. It is the largest European true bug and aquatic insect. Adult females are typically 7–8 cm (2.8–3.1 in) long, while the adult males are 6–7 cm (2.4–2.8 in).
Belostoma is a genus of insects in the hemipteran family Belostomatidae, known colloquially as giant water bugs. Members of this genus are native to freshwater habitats in the Americas, with the greatest species richness in tropical South America. Most species in the family Belostomatidae have historically been included in Belostoma, but several of these have been moved to other genera. 9 species are claimed to be found in Northern America, but the genus Belostoma is actually divided into 16 subgroups containing about 70 species.
Ant eggs refer to both the eggs and pupae of weaver ants eaten in several countries across Southeast Asia, especially Laos and Northeastern Thailand (Isan). They are high in protein and enjoyed for their sourness and pop when eaten along with soups, omelets, and salads.
Congee is a form of savoury rice porridge made by boiling rice in a large amount of water until the rice softens. Depending on rice-water ratio, the thickness of congee varies from a Western oatmeal porridge to a gruel. Since the history of rice cultivation in Asia stretches back to the Baiyue-inhabited lower Yangtze circa 10000 BC, congee is unlikely to have appeared before that date. Congee is typically served with side dishes, or it can be topped with meat, fish and pickled vegetables.
Benacus griseus is a species of giant water bug in the family Belostomatidae. It is the only species in the genus Benacus, which was formerly considered a subgenus of Lethocerus.
