Hello, I am the presenter and we are going to talk about Coleoptera. 00:00:27

The insects that we are going to talk about are ladybugs and beetles. 00:00:32

Pablo is going to talk about ladybugs. 00:00:37

Hello. 00:00:43

Hello Pablo. 00:00:44

I am going to tell you first the characteristics of the ladybugs. 00:00:46

The first characteristic is that they can be seen between 6 and 8 millimeters. 00:00:52

Oh, that is so interesting. 00:00:58

Yes, they usually have red and orange colors with black points. 00:01:00

Oh, I don't know that they have orange color. 00:01:06

They have a particular body, the ladybugs. 00:01:09

And Pablo, would you let me ask a question that I have since I was little? 00:01:17

Yes, I'm here for that. 00:01:25

How do they reproduce? 00:01:27

They reproduce attached to the branches of trees, leaves and trunks. 00:01:29

They put yellow eggs one by one in their habitat because they need to eat leaves and something like that. 00:01:40

And they can put between 10 and 15 eggs. 00:01:57

Thank you for showing me a dog that I have when I was a child. 00:02:05

You're welcome. 00:02:13

Now I'm going to explain what they eat. 00:02:15

Ladybugs, the diet that they have, is divided into two groups, predators and phytophagous. 00:02:18

One eat plants and the other is not carnivore but eat other insects like aphid. 00:02:31

That's interesting. 00:02:41

Yes, also they get nutrients from water. 00:02:43

Thank you Pablo. And now I thought tell about the interesting facts of Lady Bird. 00:02:47

Goodbye. 00:02:56

Goodbye. 00:02:57

Hello. Tell me an interesting facts of the ladybugs. 00:03:02

Some interesting facts that beetles make up 40% of the known insects and 25% are known of the world. 00:03:08

But first we are going to tell you what is an aphid. 00:03:21

An aphid are a major pest in most fruits, crops, causing deformation in leaves, stems, and fruits, in general weakening of the plant, spots on fruit, and even in some caves, destruction of vegetative and flowering plants. 00:03:26

I thought, can you tell me another very interesting bug? 00:03:43

Yes, I can tell you. Another ladybug can eat up to 70 aphids a day, and they are predatory birds. 00:03:48

That's very interesting. 00:03:58

Yes, and they are biological insects, pest controlers in gardens and crops. 00:04:02

And I thought, what are their points? 00:04:08

They have also bones to come across predators and need for help. 00:04:10

First, I am going to say you their bodies are divided into three main parts. 00:04:16

The head, the throat and the abdomen. 00:04:24

The head. In the head, beetles have antennae and have their jaws that are strong and are adapted for chewing. 00:04:27

Thorax. The thorax is made of three segments and we have the legs located in the thorax. 00:04:42

They have also six legs and additionally the thorax is covered by Elytra. 00:04:52

That is a hardener that protects the another wings. 00:05:00

The abdomen, that is the last part that I am going to explain of morphology. 00:05:06

The abdomen is the rare part of the body that can have reproductive organs or internal systems. 00:05:13

Oh, that's a very interesting thing that I don't know. 00:05:22

And now I am going to show you an example of a beetle. 00:05:26

So, this is the beetle. Here you can see the wings, the head, the legs, and here you can see a lot of things of the beetle. 00:05:31

So the diet are herbivores, carnivores and detritivores. 00:05:50

Herbivores can eat some leaves, wood or plant foods. 00:06:01

Carnivores eat some animals or insects. 00:06:09

And detritivores, they eat breakdown dead organic matter. 00:06:13

Really, they are detritivores? 00:06:19

Yes, at the beginning I also didn't know. 00:06:22

What is the life cycle? 00:06:28

The life cycle and the reproduction, they are sexually reproduced. 00:06:31

They use metamorphosis to reproduce. 00:06:38

The first is the egg that they live in the soil, inside wood, or like in plants. 00:06:43

Second, the larva. The larva is like the warm black stage that fills and blooms. 00:06:54

The third, the pupa. It's a transformation stage, like a cocoon. 00:07:01

Therefore, there are definitely the development of beetles. 00:07:06

It's very interesting process. 00:07:13

Her survival strategies? 00:07:16

Her survival strategies are that some beetles can camouflage or mimic other animals. 00:07:18

They also can release toxic chemicals. 00:07:25

That's amazing. 00:07:32

her social behavior. Her social behaviors are that most beetles live in solitary lives, but 00:07:34

certain beetles can live in small groups. And this is the end that I am going to tell you. 00:07:43

Bye, thank you. Bye. To enter to tell us the interesting facts of beetles. Can you tell me 00:07:51

The first interesting fact is that beetles make up 40% of unknown insects and 25% is for unknown animals on earth. 00:08:02

The second is the biggest and the smallest beetle. 00:08:16

The biggest is the titan beetle which is 17 cm long and it is similar compared to a hand of this size. 00:08:22

And the smallest is the nanosella, that is the smallest, and grows up to 1.3 mm, and each comprises the size of a grain of sand. 00:08:30

The third interesting fact is that the rhinoceros beetle can lift up 850 of its own weight. 00:08:46

And that's similar to a human lifting 60 tons. 00:08:55

The fourth interesting fact is that fireflies are actually a type of beetle that produce light as well as intense light. 00:09:00

Thank you. Can you tell me five interesting facts? 00:09:12

Yes. The last one is that the Bombardier beetle, which is now a Brachynus, 00:09:18

sprays a boiling pot as a chemical explosive at predators. 00:09:25

Thank you. 00:09:30

Thank you very much. 00:09:31

Bye. 00:09:33

Bye. 00:09:34

And this is the end of the program. 00:09:35

and that's it this is the end of my okay and this is the end of water and what i 00:09:52

and paulo would you let me ask a question that i have since i was very little 00:10:11

Yes. They usually have red and orange colors with black points. 00:10:16

Oh, I don't know that they have red and orange colors with black points. 00:10:26

The first characteristic is that they can measure between 6 and 8 millimeters. 00:10:33

Oh, that's so interesting. 00:10:51

The first... 00:11:01
