Striped bark scorpion

Centruroides vittatus

只是會痛會痛，但不會對你造成嚴重傷害。

螫吃：肉

The striped bark scorpion is a medium-sized, pale yellow scorpion with two dark stripes along its back. It lives across the middle of the United States and in northern Mexico, and it is perhaps the most often seen scorpion in the US. Its sting is painful, but it is very rarely deadly.1

It lives in deserts, deciduous and coniferous forests, and temperate grassland. By day it hides under rocks and surface debris, in vegetation, and in old sheds, barns and houses. Thousands of people are stung each year, often while barefoot or when they touch it by accident in houses and other buildings.1

牠吃什麼？

It eats insects, smaller arachnids and even young of its own kind. It forages on the ground or in vegetation at or after sunset, when it leaves its daytime shelter.1

毒液力量

毒液從螫針出來。

牠的毒液有什麼作用？

Its venom contains neurotoxins, which attack the nerves. These can cause tingling and numbness (paresthesia) and muscle spasms. One toxin keeps pain-sensing nerves firing for longer than normal, so the pain lasts. In rare severe cases, the venom can trigger a strong allergic-type reaction, with swelling, breathing trouble and, in the most severe cases, anaphylactic shock.1

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。

Thousands of people are stung every year. The sting is painful and causes localised swelling, and it is very rarely deadly. Severe allergic-type reactions have occurred in some cases.1

如果牠螫人

Swelling can be treated with an ice pack. Get medical help straight away if symptoms are strong, because stings from some related bark scorpions can be deadly.1
用冰敷袋冰敷螫傷處，讓傷者保持不動。趕快就醫，特別是小朋友：有些蠍子對小孩是致命的。

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。
如果被牠螫了：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

Before mating, males hold a showdown, waving their tails until one backs down. The winner then performs a courtship dance called the promenade a deux, in which larger males usually succeed.1

Unlike most scorpions, this species is social, so males and females have more chances to meet and compete for mates.1

In Colorado, people hunt for these scorpions with blacklights each late summer around the Cheyenne Mountain area.1

Populations have been found in some cities far outside its natural range, most likely brought there by human activity.1

Birds, reptiles, some mammals and larger arachnids prey on it, and juveniles spend much of their time in vegetation to avoid being eaten.1
