Nectar robbery, in which a bumblebee carves a hole in the side of a flower as a bank robber might cut his way into a vault, was discovered by Charles Darwin.

某些花的形状发生了演化，以促进具有的昆虫为其授粉。昆虫的探到狭小管道状花的深处。达尔文（Charles Darwin）最先发现熊蜂“抢劫花蜜”的行为。

Addie said the bumble bee and the yellow bumble bee when they're not under the microscope look pretty much the same except one's bigger than the other.

艾迪说熊蜂和黄蜂不在显微镜下看差不多，只是一个比另一个大一点。

Roses evolved their aromas millions of years before humans even existed on this planet, mostly to speak to bumblebees and other insects.

早在人类出现在地球上的数百万年前，玫瑰就演化出了香气，主要是为了与熊蜂及其他昆虫“交流”。

These look like the eastern bumblebee, bombus impatiens, and they are putting their tongues into the front of the flower.

这些看起来像东方大黄蜂，熊蜂，它们把头伸进花朵的前面。

And it turns out, a bumblebee might have a similar feeling, buzzing through a field of flowers.

事实证明，熊蜂在嗡嗡地飞过花田时，可会有类似的感觉。

Times up, bumblebees, if you please, belong to the genus Bombus.

时间到了，大黄蜂，如果你也这么认为的话，属于熊蜂属。

Some bumblebees do have such tongues. But some do not.

有的熊蜂的确有，不过有些确实没有。

And now Leonard and her colleagues have discovered that bumblebees are pollen aficionados, too.

现在伦纳德和她的研究团队发现，熊蜂也是花粉爱好者。

But bumblebee populations can be bolstered.

不过，熊蜂种群依然有机会得到恢复。

This technique lets bees get at the nectar of flowers whose shapes have evolved to encourage their pollination by insects with long tongues, which can reach down narrow tubes.

熊蜂在花的一侧切开一个口，行径无异于银行强盗杀进金库。它们凭借这种本领获取狭小管道状花的花蜜。

They painstakingly recorded the sites of robbery holes in yellow-rattle flowers, and studied the behaviour of 168 bumblebees.

他们煞费苦心地记录yellow rattle上“抢劫孔”的位置，并且研究了168只熊蜂的行为。

Moreover, if one species was behaving in (say) a left-handed manner in a particular meadow, the other was likely to do the same.

更有甚者，如果针对特定的草场，一种熊蜂（假设）是“左撇子”，那么另一种熊蜂通常也是“左撇子”。

Dr Goulson found, as he reports in Behavioral Ecology and Sociobiology, that two short-tongued bumblebee species which live in the area, Bombus lucorum and Bombus wurflenii, demonstrated handedness when they robbed flowers.

Goulson博士发现，就像他在《生态与社会生物》上发表的，生活在该地区的两种短熊蜂（Bombus lucorum 、Bombus wurflenii）在打劫花时表现出“利手”（用右手或左手的习惯）行为。

The question about nectar robbery that has intrigued biologists from Darwin onwards is whether the behaviour is innate or learnt.

熊蜂抢劫花蜜的行为到底是先天性还是后天性，自达尔文起，生物家们一直对此感到困惑。

Which of these insects belongs to the genus Bombus?

以下哪种昆虫属于熊蜂属？

About 250 species of bumblebees live across the globe. They're most common in temperate regions. But some can be found in the tropics and even in the Arctic.

全球约有250种熊蜂。它们在温带地区最为常见。但在热带甚至北极也找到它们。

When we think about pollination, we may have honeybees in mind, but bumblebees and hoverflies and wasps and moths and butterflies and beetles also pollinate.

当我们思考授粉时， 脑海中可会浮现蜜蜂的形象，但实际上， 熊蜂、食蚜蝇、黄蜂、蛾类、蝴蝶以及甲虫也同样参与授粉。

And if he's not here and then, but my husband always calls me a little bumblebee and a butterfly.

而如果他不在这里，但我的丈夫总是叫我小熊蜂和蝴蝶。

And, uh... And then... And... And... And... And... And... And honey bear needs to be able to come with.

而且，嗯… … 然后… … 接着… … 接着… … 接着… … 接着… … 接着… … 小熊蜂蜜罐也得一起带来。

Small bumblebees are flying all over the plate. We call to the bumblebees as they buzz near the plane.

• 小熊蜂在盘子里飞来飞去。当大黄蜂在飞机附近嗡嗡作响时，我们呼唤它们。
