怎样认出它

Typically 6.5 to 8 cm long.1
Its abdomen has glands that produce odorous chemicals.1
Some of these chemicals give a sweet, banana-like smell.1

常被误认为： Lethocerus patruelis has narrower light stripes on the pronotum (the plate behind the head). Lethocerus insulanus has a dark stripe between its light stripes. Kirkaldyia deyrolli is paler and has no pronotal stripes, and its eyes are set further apart.1

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。

如果被它咬了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

事实

In several Southeast Asian cuisines it is a well-known edible insect. Its flight muscles are often said to taste like sweet scallops or shrimp.1

In Vietnam, a single drop of the extract on a toothpick is enough to flavour a whole bowl of bún thang soup.1

In Vietnam, its scent essence is a pheromone produced by males that attracts females. It is collected from liquid-producing sacs and sold in small glass containers.1

Much of the essence sold as cà cuống in Vietnam is imitation, because the real product is scarce and expensive.1

Its large size, flight muscles and easy dissection make it a model for studying muscle structure, especially cardiac muscle.1

In Northeast India, it is often fried or made into a chutney. It is valued for its high protein content.1
