The eastern cicada killer is a large wasp that hunts cicadas, the loud insects that buzz in summer trees. It lives in the Eastern and Midwest United States and further south into Mexico and Central America. Females are not aggressive and rarely sting, so the sight of them flying over lawns is usually harmless.1

它吃什么？

Females catch cicadas and paralyse them with a sting, then carry them to their burrows as food for their young. Adults also feed on flower nectar and plant sap.1

怎样认出它

Large, at 1.5 to 5.0 cm long1
Hairy thorax with reddish and black areas1
Black to reddish brown abdomen marked with light yellow stripes1
Brownish wings1
Females are somewhat larger than males1

常被误认为： Its colours resemble some yellowjacket and hornet species, and European hornets are often mistaken for it. European hornets are about 3.5 cm long, so they are smaller than the largest cicada killers.1

毒液之力

蜇伤

毒液通过蜇刺出来。

它的毒液会造成什么？

The female's sting paralyses cicadas so that they can be stored as food for the young.1

它对人有多危险？

对人的危险: 轻微像被蜜蜂蜇一下或更轻。对人基本无害。

Females are not aggressive and rarely sting unless they are grasped roughly, stepped on with bare feet, or caught in clothing. One author who was stung said the sting felt like not much more than a pinprick. Males cannot sting.1

它害怕时会做什么？

Females sting only if handled roughly. Males may jab with a sharp spine on the tip of the abdomen if handled roughly, but they usually fly away when swatted at.1

如果它蜇人

刮掉蜜蜂的蜇针，冷敷患处。
如果这个人呼吸困难、脸或喉咙肿胀，或感觉要晕倒，这是过敏急症：拨打急救电话，如果他们有肾上腺素笔就使用。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

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。
如果被它蜇了：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

A female often carries a cicada up into a tree before flying to her burrow, because the cicada can weigh more than twice as much as she does.1

Males are seen in groups and may lock together in midair combat until one breaks away.1

Cicada killers may help trees by reducing the number of cicadas that feed on them.1

The parasitic velvet ant wasp, also called the cow-killer wasp, often lays its egg in cicada killer nest cells.1

A single burrow may eventually have 10 or more nest cells.1

谣言粉碎机

谣言： Male cicada killers are dangerous and will sting people.

真相： Males only grapple with other insects and cannot sting. They investigate things that move near them because they are looking for females.1
