怎样认出它

Adults are uniformly dark brown to black and measure 17–22 mm in length.1
The head is elongated, with a short, three-segmented beak and long, slender antennae.1
The abdomen is wide and extends beyond the wings in the middle, showing the edges of its abdominal segments.1
Nymphs look like small adults but are often grey or light-coloured, because a sticky body coat collects dust, lint and small particles.1

常被误认为： Masked hunters are sometimes mistaken for the kissing bug. Unlike the kissing bug, masked hunters do not carry Chagas disease.1

咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

A handled or trapped masked hunter can deliver a rostral stab, which is painful and comparable to a bee's sting. The swelling can last for about a week. They do not feed on human blood.1

它害怕时会做什么？

When handled or trapped, it defends itself by delivering a stab with its beak.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。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
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

值得了解

事实

Nymphs build two layers of camouflage on their bodies, an inner layer of fine particles and an outer layer of coarser ones, using their hind legs and a tarsal fan.1

Their sticky body coat catches dust, lint and other small particles, which hides them from both predators and prey.1

Because they hunt bed bugs, a masked hunter in the home can be a sign of a bed bug problem, and controlling the bed bugs usually deals with the hunters too.1

Masked hunters were probably introduced to North America by accident in the late 1800s to early 1900s. They were first found in Canada in 1905 and in the United States in 1917.1

谣言粉碎机

谣言： Masked hunters are kissing bugs and carry Chagas disease.

真相： Masked hunters are sometimes mistaken for kissing bugs, but they do not carry Chagas disease. Their stab is painful, but it does not spread that disease.1
