The common eastern bumblebee is a furry, black and yellow bee. It is the most commonly seen bumblebee across much of eastern North America, including towns, cities and fields. Its visits to flowers help pollinate many crops, so it matters to farmers and gardeners.1

牠吃什麼？

They feed on pollen and nectar from many flowers, including clover, goldenrod, rose and blueberry plants. Most bees in the colony eat honey, which they make by swallowing pollen and nectar and mixing them with enzymes in their stomachs.1

怎麼認出牠

Queens and workers are black with a yellow thorax (the middle part of the body) and a yellow first abdominal segment (the first part of the rear body).1
Males have a yellow face and head, and their coloring is slightly different from queens and workers.1
They have short, even hair and a long, rectangular body.1
Queens are the largest, at 17 to 23 mm long. Workers measure 8.5 to 16 mm and males 12 to 18 mm.1

常被誤認為： They look similar to Bombus bimaculatus, B. perplexus, B. vagans, B. sandersoni and B. separatus.1

牠對人有多危險？

對人的危險: 輕微跟蜜蜂螫差不多或更輕微。對人基本上無害。

如果牠螫人

把蜜蜂的螫針刮掉，然後冷敷患處。
如果傷者呼吸困難、臉部或喉嚨腫脹，或覺得快要昏倒，這就是過敏急症：打緊急電話，如果傷者有腎上腺素自動注射筆，就使用它。

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

牠有多快？

一隻家蠅 大約 7 km/h (4,4 mph)

Common eastern bumble bee 大約 25 km/h (16 mph)

值得知道

小知識

Queen bees can stay underwater for up to a week without drowning, which may help them survive floods or wet winters.1

Foragers use traplining, visiting flowers in the same repeatable order. This saves time and energy.1

Foraging bees share information about good food sources with other bees in the nest.1

Inside the nest, smaller workers stay near the centre and feed the young, while bigger workers work as foragers and guards on the outside.1

Commercially raised colonies are used to pollinate tomatoes, blueberries, raspberries and pumpkins in greenhouses.1
