Something Really Big

Here's something really simple but really BIG that you can do to help the bees.

It's really easy too.

Ask your parents, grandparents, teachers, friends and neighbours to let the dandelions bloom.



Many people don't like dandelions and that's okay. Ask them if they could just wait until the flowers die, before they go to seed to cut them down with the lawn mover or to pull them out.



That way the bees would get some time to visit them.


[Do you think this bee is using the cell phone to tell people about Dandelions? She might be....]

Dandelions are one of the best spring flowers to bloom that offer lots of pollen for hungry bees. After winter the bees need lots of protein for their babies and dandelions offer the perfect food for bees.



And if you were hungry you could eat the leaves in your salad. And you can roast the roots. Some people even make wine from them.

The more you think about dandelions the more they seem like the perfect flower food for everybody.



Before we looked at the importance of pollen as a protein source for growing baby bees. So doing this one small thing--letting the dandelions bloom--will end up being a really big thing for bees.

I just know the bees want to say thank you for helping.

Predators in the Garden

Have you heard the saying, "Busy as a Bee"?

Honey bees are well known for keeping themselves busy gathering nectar and pollen and caring for their young.

They forage in the garden with a focus on gathering as much food as they can for their family back in the hive.

It's a busy and difficult life for a bee. And sometimes it's downright dangerous.

To you and me a bee is an insect but to many others they're a nice juicy protein snack. That's right, they're a good meal for a hungry predator.

There are many predators in the garden that feed on insects like bees. Most of them are also insects. That doesn't seem fair does it?

Can you think of an insect predator? Yes, a spider.

Spiders are very good hunters that help to control insects in the garden. Their sticky webs can often catch a bee.

Or they'll hide lie in wait for a bee. This white crab spider hid under the petals of the purple cone flower. The bee can smell the nectar and pollen offered by the flower and so she lands on the flower. Before she knows what's happening the spider leaps out and grabs her and gives her a poisonous bite.

Sadly it's all over for the bee. She's become a spider's meal.

In the photo above can you see the white spider hiding on the purple flower?

Another larger predator of bees is the large dragonfly (pictured at left). They can catch a bee in mid air. Hornets too are much larger and stronger than bees and will catch them and eat them.

Then with their strong mandibles (mouthparts) they'll bite the bee's head off, killing it.

Other garden predators are the preying mantis. This stick-like insect (pictured at left) can sit very still, looking like an innocent leaf. Then it'll spring forward when a bee lands close by and catch it with it's claw-like arms.

Birds will catch bees in flight and eat them too. Frogs and toads have long tongues that can lash out and catch them.

Mammals like raccoons, skunks and bears love to eat bees and bee larvae too.

Everywhere the bee goes she's in danger of becoming a meal.

And finally, other predators will feed off the dead bee corpses, insects like ants or rodents like mice.

The death of a bee is sad but the good thing is that in nature nothing ever goes to waste and her body will nourish other creatures who are in need of a meal.

The Birds and The Bees

Let's talk about the birds and the bees.

They have a lot more in common than you might realize.

Think about something that both birds and bees can do.

They both have wings and they can fly.

Bees have something else that birds have but you'd need to look close, very close and use a magnifying glass to see.

Bees have feathers.

What? It's true. They do.

When we look at bees we see their lovely golden fur. We say things like 'fuzzy bee'. They do look fuzzy.

If you magnified the hairs on a bee you would see they are actually plumes just like the feathers on a bird, only much more delicate.

The fur or feathers keeps the bee warm on cold days and during the winter.

These feathers are perfectly designed. They are light and airy so the bee can fly.

They are thick and warm so the bee can retain her body heat and survive through the cold winter.

Last time we looked at how a bee uses her fur to collect pollen through static electricity.

Now you can see why bees of a feather stick together!

Electric Bees

Have you seen the commercial on TV advertising the Swiffer sweeper?

The swiffer has a cloth that glides across the floor and the bits of dust and debris can't help themselves. They attach themselves to the Swiffer like a magnet.

But what does this have to do with bees? Bees and the Swiffer have a lot in common. If you've ever been to a birthday party and played with balloons then you're like bees and a Swiffer too.

Have you ever rubbed a balloon on your hair and then stuck it to your body? When you rub it you create static electricity.

When the Swiffer rubs across the floor or an object, it creates static electricity too.

Static electricity is like a magnet to little particles like dust..... or something similar to dust.... Pollen.

When a bee flies through the air static electricity builds up in her fur. Then she lands on a pollen covered flower.

The tiny particles of pollen can't help themselves, like magnets they are drawn to the bee and attach themselves to the bee's fur.

This makes it easier for the bee. She'll sweep her legs over her body to collect the pollen.

Then she'll take some of her spit to moisten it to make a lump.

She'll stick the lump to stiff hairs (called pollen baskets) on her back legs.

After that she'll fly home with her load.

So next time you see a Swiffer sweeper, pretend like a bee and give it a try.

Imitation is the Best Form of Flattery

Who do you admire the most in the whole world?

Is it a movie star or a famous singer? A teacher? Your older brother or sister? Or your hero?

Have you ever been tempted to act or dress like them?

If so then your thinking isn't very different than a whole lot of insects.

You see many insects admire bees and wasps. It's because they have stripes which are very fashionable in the insect world... and they have stingers.

Stripes are a warning to others: I have a stinger so don't mess with me!

Have you ever worn striped clothes? If so, you are copying bees and letting everyone around you know that they should be careful.

You might have a stinger too.

Copying is popular in the insect world. It's called insect mimicry.
Insects use mimicry as a disguise to hide like pretending to be a leaf or a tree branch or to scare other insects away with painted big eyes or by releasing a terrible smell.

There are lots of flying and crawling insects that don't have stingers or venom but they want to have stripes so they look like a bee or a wasp. Can you guess why they'd want to look like that?

So that other insects will be afraid of them and think they have a stinger.

[This picture from the Wikipedia web site shows several stingless insects pretending to be wasps].

Next time you're in the garden and you see a striped insect, take a closer look.

Is it a bee or a wasp or another insect pretending to be one? It may well be a little harmless fly, pretending to be a bee.

HONEY

We know that bees collect flower pollen. We know that flowers deliberately attract bees by offering nectar.

The bees put their tongues into the flowers and suck up the nectar.

And we know that the bees fly back to the hive with that precious nectar.

But what happens after that? They make honey!

Let's go inside the hive and find out how the bees do it.

When a bee first arrives back at the hive, she's flying heavy. Her stomach is full of nectar. She'll often be greeted by a house worker bee at the entrance.

She'll unload her nectar to the house bee. They touch tongues and the field bee will release the droplets of nectar to a house bee. Once her stomach is empty the field bee will go back out again to collect another load.

The house bee will climb the frames of comb to the honey area. Once there she'll regurgitate droplets of the nectar to the tip of her tongue. She'll hold them there.

Why does she do that?

She's letting the warm air inside the hive dry up the liquid in the nectar. She'll hold droplets a few times and then she'll dunk down inside the cell and regurgitate all the nectar.

After that she'll go back down the hive to wait for another field bee to come in with another load of nectar.

Next will come more house bees. These will be fanning bees. Their job is to beat their wings to create wind that will blow on the nectar and dry it up. As the liquid evaporates the bee magic begins.

The nectar becomes thicker and thicker. It becomes sweeter and sweeter. The bee might even taste it just to be sure. Mmmmm. It's good. She knows exactly when the honey is thick enough--ripe enough--to be done.

Then more house bees will come. They will be capping bees that can make wax. They'll put lids on the honeycombs to store the honey just like how we store food in jars.

[Picture at left - The yellow stuff in the cells is pollen. The shiny liquid is honey].

When the flowers have faded and winter comes bringing cold winds and snow, the bees will snuggle together in their hive to keep warm.

And while they warm themselves all through the cold months of winter they'll have lots of food--honey.

Honey made from a flower's nectar.

A Flower's Secret: Candy for Bees

Doesn't everybody love sweets? Bees certainly do.

I suppose you could call flowers pros when it comes to making sweets. They make a nectar that bees love just like we love candy.

Last time we looked at flower pollen and how the bees use it as a food for the hive. We examined the special relationship that flowers have with bees. They need help spreading their pollen and the bees are happy to do that for them.

But why do many flowers also make nectar? It's their secret trick: Advertising.

What? Yes, it helps for flowers to advertise to bees.
There are many, many flowers in bloom in summer and the flowers compete to get the bees to come to them and not to the other flowers. They try to make their nectar smell and taste the best. And it works.

The bees have an amazing sense of smell (they sniff with their antennae) and that's how they find which flowers are offering the sweetest smelling nectar.

The bees come and suck up the nectar with their long tongues. And while they're at it the flower's pollen collects on their fur. That's how flower's guarantee their pollen seed gets spread around.

Almost all plants that rely on insect pollination produce both pollen and nectar.

Nectar looks like water except it's sweet. It tastes and smells like flowers which is what gives honey its special flavour and colour.

The bees are happy to have their nectar but they still have to make it into honey. Next time we'll look at how bees turn nectar into honey.
