Masked hunter

Reduvius personatus

名字的由來： The name comes from the nymphs' habit of camouflaging themselves with dust, which hides them like a mask.1

只是會痛會痛，但不會對你造成嚴重傷害。

咬吃：肉

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

The masked hunter is a dark brown to black insect from the assassin bug family. It hunts small creatures such as bed bugs, woodlice and termites, and it is often found in homes. Its nymphs hide by covering their bodies with dust and debris.1

Masked hunters prefer dry habitats. People usually meet them when they infest houses, often in homes with bed bug infestations, where they are usually found in small numbers.1

在陸地上, 粗略估計

牠吃什麼？

Adults and nymphs both hunt other arthropods, including woodlice, lacewings, earwigs, bed bugs and termites. They pierce their prey with sucking mouthparts, and they hunt bed bugs at night.1

怎麼認出牠

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

常被誤認為： Masked hunters are sometimes mistaken for the kissing bug. Unlike the kissing bug, masked hunters do not carry Chagas disease.1

毒液力量

咬

咬的時候，毒液會從毒牙或牙齒出來。

牠對人有多危險？

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

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

牠害怕時會做什麼？

When handled or trapped, it defends itself by delivering a stab with its beak.1

如果牠咬人

被會螫人的毛毛蟲毛刺到時：用膠帶把毛黏起來，再清洗皮膚。不要搓揉。
被咬時：清洗並冷敷。如果傷者覺得不舒服或容易流血，要就醫。

一定要先打緊急電話（112、000、911）。這是一般急救指引，不是醫療建議。急救基本知識

注意安全

絕對不要碰、抓或捉弄野生動物，就算是很小的動物，就算牠看起來在睡覺或已經死了也一樣。
給牠空間。如果遇到了，保持冷靜，慢慢往後退，讓牠自己離開。
如果被牠咬了：保持冷靜，保持不動，打緊急電話（112、000、911）或趕快去醫院。記住牠的樣子，有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己，而且牠更想躲起來。更多安全知識

小知識

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

破解迷思

迷思： 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
