Here are some of them.0:33
Bees are social insects.0:40
They live in big groups or colonies.0:42
Each colony has a queen bee and worker bees.0:45
A worker bee's life is very short.0:48
Usually about four weeks work a bee's fly and collect nectar from flowers.0:51
A bee can see some colours.0:56
They are green, blue and ultraviolet, which people cannot see.0:59
But red is not a color to a bee.1:04
It sees red things as black.1:07
By the way, a bee must visit about 4,000 flowers to make a tablespoon of honey.1:10
Worker bees are very busy insects.1:16
People often say as busy as a bee about someone who has a lot of work to do.1:19
Ants are social insects too.1:29
They are colony makers and have been living on the earth for about 100 million years.1:32
Their number is very large.1:38
You can find ants in forests and mountains, in plains and valleys, nearly everywhere on our planet.1:40
Some colonies are on the ground and others live deep in the ground.1:48
Most ants are wingless, but their queens usually have wings.1:53
Ant workers get food for the queens.1:57
Ants are very hard working insects.2:00
Butterflies are flying insects.2:07

They change their skin several times as they grow.2:36
Then a caterpillar turns into a chrysalis from which a butterfly comes out.2:40
Some butterflies fly from one part of the world to another during some seasons.2:46
