这只蜜蜂忙着在泥里刨啥?
What’s this bee up to digging around in the mud?
这只蓝果树蜂是一名泥瓦匠 一位建筑师
This blue orchard bee is a mason, a builder.
她用的材料 你猜着了 是泥土
Her material is – you guessed it – mud.
她是单独行动的
And she works alone.
实际上 不像你脑海中可能浮现的蜂群
In fact, unlike those honeybee hives you might think of,
北美4,000多种蜂中的大部分都是独居的
most of the 4,000 types of bees in North America are solitary.
看看她是如何刮下湿土的?
See how she scrapes the wet earth?
她用被称为“大颚”的器官挖土
She collects it with two huge pincer-like tools
就是脸上两个钳子似的巨型工具
on her face called mandibles.
她正为筑巢而收集泥土
She’s gathering mud to make her nest.
她的巢穴长而窄
The nest is long and thin.
在自然界 她在空心树枝这类地方筑巢
In nature, she goes into places like hollowtwigs.
而在加利福尼亚大学戴维斯分校
At the University of California, Davis,
她则利用研究者们提供的六英寸长纸管来筑巢
she uses a six-inch-long paper straw provided by researchers.
从这座无纸管的巢穴中
In this nest without a straw
可以看到她是如何建造泥墙的
you can see how she builds a wall of mud.
然后她从春天的花朵中觅食
Then she gathers food from spring flowers,
但不仅是为了自给自足
but not only to feed herself.
看到这朵花的花药上诱人的紫色花粉了吗
See the pretty purple pollen on the anther of this flower?
她用腿抓住花药
She grabs the anthers with her legs and rubs the pollen
将花粉蹭到腹部称为“腹毛刷”的毛上
onto hairs on her abdomen called scopa.
与此同时
And while she’s at it,
她从花朵中啜取了一点花蜜
she sips a little nectar from the blooms.
爬回自己的巢穴后
When she climbs back into her nest,
她把花粉和花蜜变成了泥墙旁的小甜点
she turns the pollen and nectar into a sweet morsel next to the mud wall.
她在这颗紫球球上产了一粒卵
On this purple ball she lays a single egg.
然后在狭窄的洞穴中重复了几次上述操作
She repeats this several times in her narrow nest.
卵 墙 卵 墙
Egg. Wall. Egg. Wall.
完成之后 她又用泥把一切封好
When she’s done, she seals it all up with more mud.
这座巢穴的横截面展现出她惊人的技艺
A cross-section of the nest shows her incredible craftsmanship.
它看起来就像一件珠宝
it looks like a piece of jewelry.
很快 这些卵就孵化了
Soon, the eggs hatch.
饥饿的幼虫以花粉存粮为食
The hungry larvae feed on their pollen provision,
这是蜂妈妈打包给它们的便当
the purple lunchbox their mom packed for them.
仍是在巢穴的庇护下
Still in the safety of the nest
吃饱喝足的幼虫织了一个茧
the well-fed larva spins a cocoon.
在随后的春日时光里 成虫破茧而出
The following spring, the adult bee chews its way out.
顾名思义
Just like their name says
“蓝果树蜂”热爱果园
blue orchard beeslove orchards:
特别是杏花和甜樱桃花盛放的果园
fields of almonds and sweet cherries.
它们也很擅长给果树授粉
And they’re really good at pollinating them:
几百个雌蜂能授粉的杏花数
A few hundred females can pollinate
相当于上千只蜜蜂的工作量
as many almonds as thousands of honeybees.
管状的巢穴意味着方便人携带
And their tube nest means they’re portable.
所以在农场里饲养蓝果树蜂更方便
That makes it easy to distribute them to farmers.
那么蓝果树蜂为什么并未“占领”农场呢?
So why haven’t they taken over the fields?
这是因为 它们繁殖得太慢
Well, they reproduce slowly.
它们每年只生十五个宝宝
They only have 15 babies a year.
而蜜蜂的蜂后一天就能产五百个卵
A queen honeybee has 500… a day.
因此蓝果树蜂并不多见
So there just aren’t that many blue orchard bees around.
但是一些农民还是养着它们
But some farmers are enlisting them anyway,
希望蓝果树蜂能够减轻
hoping they can provide some relief
它们忙碌蜜蜂表亲的负担
to their struggling honeybee cousins.
如果你仔细看
If you look carefully
也许就能在田间发现一只采蜜的蓝果树蜂
you might just spot a blue orchard bee foraging out in a field,
正帮忙培育各种果子给我们吃呢
helping keep fruits and nuts on our plates.
嗨 我是劳拉
Hi, It’s Laura.
