Eastern carpenter bee

Xylocopa virginica

无害对人无害。不用担心。

蜇伤吃：植物

The eastern carpenter bee is a large bee that lives across eastern North America, from the eastern United States into southern Canada. It digs its nests into wood, often in buildings and furniture, so people can come across it close to home. Its nests are social, with groups of females sharing one entrance.1

它吃什么？

It feeds mostly on nectar and pollen. Some long-tubed flowers are pierced at the base with its sharp jaws to reach the nectar, which can bypass pollination.1

怎样认出它

Similar in size to a bumblebee1
Glossy, mostly black body with a slight metallic purple tint1
Males have a longer body and a white spot on the face1
Females have a wider head1

常被误认为： It is similar in size to bumblebees, so size alone is not enough to tell them apart.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。

它害怕时会做什么？

Males guard territories near the nest entrance and chase fast-flying intruders.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

Mating happens only once a year, in the spring, and often includes a bobbing dance by a group of males.1

The bees can recognise each other and show more aggression toward bees from other nests than toward their own nestmates.1

Young bees are white when newly emerged and their wings darken over several days, first to brown and then to a bluish black.1

Dominant females do almost all the work in a nest, including reproduction, foraging and building, while subordinate bees mostly guard the nest.1

Old bees die by early August, around the time that new young bees emerge, so there is little overlap between generations.1
