00:00Hello friends, welcome to a new happy learning video.
00:13Did you know that for every four animals three of them are insects?
00:18We calculate that for every human being there are 200 million insects.
00:24We are surrounded by insects, so I think it's important to get to know them a little more.
00:36Insects are invertebrate animals that share a number of characteristics.
00:43Their body is divided into head, thorax and abdomen.
00:49They have two antennae, six legs and breathe through their trachea.
00:55From the moment they are born, insects undergo a series of body changes called metamorphosis.
01:03Most insects are oviparous and maggots are born from the eggs.
01:09As we can see in the images, they don't look anything like their parents.
01:15They look like worms.
01:17When they grow, they enclose themselves in a cocoon they make with a substance called silk.
01:25Inside the cocoon, they undergo an incredible change in their bodies and they exit as adult insects.
01:34This metamorphosis stage is called pupa, although when referring to butterflies we call it chrysalis.
01:46The large majority of insects have wings.
01:50In fact, they are the only group of invertebrates that can fly.
01:56Another shared characteristic amongst insects is that they have almost perfect vision.
02:06They have compound eyes.
02:08It's as if they had hundreds of tiny eyes in each eye, which provides excellent peripheral vision.
02:16As we said before, there are so many insects and there are also many types.
02:28There are very annoying insects like head lice, flies or mosquitoes.
02:40Interesting insects because of their shape like stick insects or leaf insects.
02:48Beautiful ones like butterflies or dragonflies.
02:54Or singer insects like a grasshopper or cricket that besides from singing is an excellent jumper.
03:06But do you know my favourite insect?
03:12It's a bee because I love the honey they make.
03:18Some insects, like ants or bees, live in highly organised societies where they each have a job assigned.
03:30The queen ant, for example, is in charge of laying eggs.
03:35Drone ants protect the nest.
03:39And worker ants are in charge of getting food and taking care of maggots.
03:47The truth is insects are incredible and although by their size they might seem unimportant, they are fundamental for nature's balance.
04:01For example, they are in charge, along with some birdies, of pollination.
04:09Some insects, like my beloved bees, are constantly flying from flower to flower, transporting pollen from one flower to the next, fertilising them, which makes new amazing plants come to life.
04:25The truth is, most insects, like most living things, are marvellous.
04:33Don't you think?
