Belostoma indicum

Lethocerus indicus is a giant water bug in the family Belostomatidae, native to South and Southeast Asia, as well as southeast China, Korea, the Ryukyu Islands and New Guinea. 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.

Lethocerus indicus typically has a length between 6.5 and 8 cm (2.6 and 3.1 in).

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. 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, 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.
