怎样认出它

Adults are 2.0 to 2.5 cm long.1
The head, thorax and front of the abdomen are black.1
The rear part of the abdomen is red.1
The wings have a violet or bluish shine.1
Males have longer antennae than females.1

常被误认为： Triscolia ardens is coloured much like the subspecies S. dubia haematodes. The forewing of S. dubia haematodes has two submarginal cells, while Triscolia ardens has three.1

毒液之力

蜇伤

毒液通过蜇刺出来。

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。

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

The young wasp develops inside the grub, pupating and overwintering in its body.1

Females dig into the ground to find beetle grubs, then sting the grub.1

After stinging the grub, the female often digs deeper to build a cell and lay an egg on it.1

Some research suggests that the Japanese beetle may also be a host for this wasp.1
