Watermelon Bugs Observation Diary Part 1

This morning, I grabbed a watermelon bug from the side of the road when I came home from school.

This watermelon bug is dark gray all over its body except for its head and tail*** which have seven segments. On each side of its head, there is a small black dot, which is its eye. Below the eyes grows another pair of tentacles that are always moving around, and the tentacles have five segments. It had fourteen legs with five segments on each leg. Like a lobster, it has a layer of "armor" on its back and only a thin membrane on its belly. Its body can bend and stretch. How many segments are there in its tail? One, two, three, four ...... not right, recount! One, two, three ...... Still not right, get a magnifying glass! One, two, three, four ...... seven, seven sections! By the way, I forgot to mention that this watermelon bug is male and has two white spots on the underside of its abdomen.

I googled it and found out that it has to survive in black soil and in places where light is hard to reach. Its food is rotting plants or cabbage leaves, and it has to put fresh food in every three days and take away the leftovers.

Seeing this, I put the watermelon bugs crawling around on my hands into the box, then dug up some black soil and put it in the box and pressed my hands to firm it up a bit.

The watermelon bugs crawled around in the box and seemed to be looking for something. I thought it was funny at first, but then I remembered that the soil I put in was too flat, and there was no way to "live" the bugs. So I put a stone in, there is a corner of the stone slightly upward, just to accommodate the watermelon bug. The watermelon bug didn't seem to see it and was still wandering around. After a while, the watermelon bug finally found the rock and hid there. Shortly afterward, it came out again, seeming to feel dissatisfied with something. When it came out, it did something that surprised me: it "nodded" its head hard on the soil, and a small pit came out. The watermelon bug swept the dirt away with its tiny feet and burrowed in.

This watermelon bug is so much fun!

Today is Sunday, I was playing with my friends at the rock pile, and suddenly found a "small ball" rolling around on the ground. My senior friends told me that this ball-like animal is called a watermelon bug.

I carefully observed the little guy: its body is about 2 centimeters long, there is a pair of antennae on the head, under the body is eight pairs of flexible feet, the back of the piece of shell like the eaves on the tile-like. Watermelon bugs like to live in a damp place, it is very good at moving, sometimes towards the sky, a few feet keep swaying; sometimes curled up, like a mini watermelon.

I think the watermelon bug got its name from this. My fingers couldn't help but flick its body, and I didn't expect it to nimbly roll over and let me pounce. Ho, this little guy, can be really interesting!

I think, in life, if we can observe carefully, we will be able to find more interesting things.

Watermelon Bugs Observation Diary Part 3

Today, the autumn high and crisp, tangerine fragrance. I went to my grandma's house to play, grandma first brought me to the vegetable field to dig wild vegetables, digging, digging, digging! Wild vegetables did not dig, but dug up watermelon bugs, I let my grandmother to bring an empty bottle, the watermelon bugs into the bottle to observe a good look ......

Watermelon bugs scientific name "mouse", also known as wet bugs, dumpling insects, belong to the invertebrates. The body is shaped like a circle, and I estimate that the watermelon bug is about 9 to 15 millimeters long. The back is slightly bulging, the stomach is flat; the color is gray-brown; the back is not soft and hard shell, I hit it it shrinks into a round watermelon, I pressed it to death, I found that its blood is white I was at a loss for words.

Blood should be red, why is the watermelon bug's blood white? This really makes people feel strange ...... I also found that the watermelon bug will not be stuck when it touches the spider's web, because it has a thin layer of oil on its shell to prevent it from being stuck by the spider's web. I heard my grandmother say: "Watermelon bugs like to live in damp, shady, dark soil and like to eat the roots of plants and are pests. Watermelon bugs have a lot to discover, research, I grow up want to be an entomologist, explore the endless wonders of the insect world!

This in my childhood, but I often play, but now the day is so cold, actually still see it, I gently touch it, it becomes a round "watermelon", no wonder everyone called it watermelon bug which. "Mom, can I keep it?" "Of course, you can." "It's great, little guy, you will be my smallest pet."

As soon as I got home, I found a little box of gum and made a transparent house for it. It was gray and black, its body was section by section, before I put it into its new home, it quickly moved its body, wanting to escape. "Where do you want to run?" My finger gently pick, it flipped over on its back, it waved its small thin legs, flip, flip, flip, flip, but how can not turn over, I then saw that it has seven legs on each side, the tail there are two small white dots, like a small eyeballs, there is a pair of antennae on the head.

Hey, I still need this "Princess" to do it. I put it into its new home, the little guy in the inside motionless, probably it is like me to enjoy the warm winter sunshine.

This afternoon, the teacher arranged for a few girls to go to help the first grade freshmen clean up. Just as we were vigorously sweeping the leaves from the wall, a voice full of surprise shouted, "Watermelon bugs! Look, there are watermelon bugs here!"

"Watermelon bugs? A bunch of little bugs, what's the fuss ......" I heard my companion mutter, my mind can not help but recall the first time I found the "watermelon bugs" in kindergarten: the grass, a dozen children gathered in a group, intently watching the "watermelon bugs", "watermelon bugs", "watermelon bugs", "watermelon bugs", "watermelon bugs" and "watermelon bugs". On the grass, a dozen children gathered in a group, intently watching the "naughty king" Tao tao found an uninvited guest - watermelon bugs. Its whole body is gray-black, body wide, flat, back covered with a layer of hard shell, shell has a clear line, under the body has a lot of small legs. Perhaps because of the fright, perhaps is not welcome to our visit, only to see it panicked east head west head to escape. Tao tao reached out to catch it, but I did not expect the watermelon bug immediately curled up into a ball, a motionless, really like a microscopic watermelon.

"I know it has seven pairs of legs." "Do you know why it shrinks into a little ball when you touch it?" "It rolls faster that way!" "No!" ...... Not far away from the first graders were arguing in a heated debate, the childish me could not help but interject loudly, "This is the insect's self-protection skills, it's faking its own death!" The answer that our kindergarten teacher told us back then, I didn't expect it to come in handy now. Looking at their curious and somewhat envious expression, my heart is beautiful.'

The little watermelon bugs, bring us how much fun!

Watermelon Bugs Observation Diary Part 6

After school, I was playing inside the yard downstairs as usual. But one afternoon I found a "little ball" rolling around on the ground. The name watermelon bugs must not be unfamiliar, it has another name, called the rat lady.

The watermelon worm is about 1 cm long, and this is only 1.5 cm, probably bigger? If you look closely, you will also find that it has 2 pairs of tentacles. It is very changeable, sometimes towards the sky, a few feet constantly shaking; sometimes curled up, a white body nodes and black or blue body called together, like a "mini watermelon". I came up with an idea to buy the watermelon bugs into a small pit, about 1 cm deep. I first take a pencil, gently put it wave guide small pit, and then some soil ash sprinkled on the pit, the pit blocked, thought, haha, now it absolutely can not come out! I squatted at the edge of the pit and watched carefully. Ten seconds ...... twenty seconds ...... thirty seconds ...... ah, the soil began to loosen! Not long after, the tentacles and little head also poked out, only the feet and body were still inside. I was very surprised and plugged the pit back up again, but it still climbed out. On the last try, I dug the pit deeper, poked it in again, covered it with dirt and ashes, and compacted it, then put a small stone on it. I thought, this time, even if it is very strong, it will not be able to come out. But I was wrong again, after a few dozen seconds, the stone and soil ash began to loosen, and in less than 3 minutes, it crawled out! It crawled out! It crawled out of the impenetrable pit! It was a miracle! And it crawled and rolled around alive and unharmed. I realized that animals have a life too, and only one. They cherish life just like we humans do.

This watermelon bug also cherish life, in order to live on, it perseveres, tenacious struggle. We need to learn from them and cherish life in order to live a better life!

Watermelon Bugs Observation Diary Part 7

One day in the summer vacation when I was in the second grade, the weather was very hot, I went to my sister's house to play, and after lunch, I came to the small garden downstairs with my sister.

I said to my sister, "Let's play watermelon bug race." Sister said, "Okay." So we started to catch watermelon bugs. Watermelon bugs hide in dark and damp corners, I spent a long time, only to catch two small. When I looked at my sister, I saw that she had already caught more than ten watermelon bugs. He had already caught more than ten. As I was getting anxious, my eyes lit up and I spotted a big, black watermelon bug. I quickly ran up and caught it, it immediately became a round "small watermelon".

We both caught a lot of watermelon bugs in a short time, and we are about to prepare for the game. The game field is surrounded by hula hoops, we use a stone as the focus. The game began, I and my sister's watermelon bugs are struggling to climb forward, but my watermelon bugs crawling crawling on the corner, I quickly take a branch to put it right. But a moment later, it ran off again, so I corrected it again. It seems that I can't catch up with my sister in this game.

I said to my sister, "Let's play watermelon bug hurdles." Sister agreed. We used small wooden sticks as rotten. My sister and I put the watermelon bugs on the starting line at the same time. "Three, two, one, go!" We let go of our hands at the same time. I saw the watermelon bugs straining to climb upward, and then dashing down sharply to dart forward. Watching them climb up and down with their bulky bodies supported by their short, thin little legs was a real go.

Time flies, and the afternoon is gone. Look at their own black dirty pair of small hands, the heart is very happy. I did not expect a small watermelon bugs to bring us so much fun.

Watermelon Bugs Observation Diary Part 8

When I was watering the flowers in the backyard, I was surprised to find a black piece under the pile of rocks in the corner, and took a closer look, oh! It was a nest of watermelon worms. I carefully moved the stones away slowly, the watermelon bugs saw the light, immediately scattered in all directions, desperately into the soil. I grabbed five of them and put them into a glass bottle.

I looked closely at the little watermelon bugs. Watermelon bugs are not as disgusting as I thought, but there are some cute. They are only half the size of an adzuki bean, gray and black body, arching back both like half a small mudball, and like a miniature bread. The watermelon bugs' backs were covered with a hard shell with a clear line on the shell. I tried to put my hand through the mouth of the bottle to touch them, they immediately tightly curled up their bodies into a small black ball, those lines make them look like a small watermelon. The watermelon bug has two tiny tentacles on its little head, which keep wiggling as it crawls. Its mouth is only as big as the tip of a pen, and the most interesting thing is that its legs are as thin as a hair, and when you look closely, you will find that these legs are grayish-white, different from the color of its back, and there are seven pairs of them in a ****. These thin legs carry a "bread", running back and forth at the bottom of the bottle. I caught a small watermelon bug and let it lie on its back on the table. This is a small watermelon is like a small boat, those tiny legs keep dancing, like a boat many small oars rowing together, interesting! Those "small oars" rowed for a long time, the "boat" neither forward, nor overturned. Finally, it felt tired, not moving, I touched it, it kept moving.

Watermelon bugs are really interesting!

Watermelon Bug Observation Diary Part 9

This day, I caught a watermelon bug.

I found this watermelon bug on my balcony, and when I saw it, it was sleeping lazily! I quietly walked over and snapped the plastic bottle down, oops! Maybe I made too much noise and it escaped, but I caught it later. I put it "prisoner" in the bottle, at first, it kept climbing up and down, after a while, it adapted to this environment.

The watermelon bug is the size of a small button, oval, with a suit of armor on its back, and a row of nice texture on the armor. Its body was black and gray, with a pair of tentacles on its head and legs as thin as hair. Its body **** has seven sections, each section has a pair of legs, climb up those 14 legs together to walk around, the speed can be slow, but it is also very cute Oh!

Watermelon bug it why called watermelon bug it? Because as long as there is something to touch it, it will immediately shrink into a ball, like a "pocket" watermelon.

Watermelon bugs like to stay in a dark and damp place, I think: they live in these places? If not, where is their home? They don't just lie in these dark, damp places, do they?

Watermelon bug it usually eat cucumber, pumpkin and other vegetables leaves, so it is not a good bug in the countryside, yo! Because it will steal the leaves of vegetables. Speaking of which, I have a question again, those who stay in the city watermelon bugs eat what? When do they go out looking for food?

At this point, the watermelon bugs were playing happily. I felt as if I had become a watermelon bug too, and was playing happily with that watermelon bug.

Watermelon Bug Observation Diary Part 10

Have you ever seen a ball rat lady? You must have seen it. What is the ball mouse woman? It is the small and inconspicuous watermelon bugs around us. Today, I will tell you about the watermelon bugs I observed.

This morning, my mom and I woke up and saw a few watermelon bugs on the ground, and immediately called my dad. Dad looked at them and said, "Maybe they were afraid of drowning when I watered the flowers yesterday, so they all crawled out." I then grabbed them one by one and put them into a small bottle, intending to raise them to observe.

Watermelon bugs like small buttons the same size, oval, back wearing a suit of armor, there are rows and rows of small lines, gray and black body, as long as the hand touch, it shrinks into a small ball, really like a "pocket" watermelon. It has a pair of tentacles on its head, with the tip of the pen gently touched, it immediately turned back. Its legs are as thin as hair, a **** seven pairs, climb up the 14 feet together, the speed is still slow, so cute.

In the afternoon, I found an interesting scene: a small watermelon bug on the back of a large watermelon bug crawling around the bottom of the bottle. I thought: this little watermelon bug must be a Hercules.

Does the watermelon bug have eyes? Can he see? I'd like to know. Does everyone know?

I love watermelon bugs.

Watermelon Bug Observation Diary Part 11

In first grade, our classroom was downstairs. As soon as the class was over, we ran into the flowerbed to look for watermelon bugs. The watermelon bugs were so small that we couldn't find them unless we looked carefully.

The watermelon bug is wearing a striped armor. It has a pair of antennae on its head, which bob up and down and side to side as it walks.

We like to get a thin string and put the watermelon bug on it. The watermelon bugs are very good at holding on to the rope and walking back and forth as gently and steadily as a goat on a tightrope.

If you hit its shell with a small stick, the head and tail of the watermelon bug will be joined together, and a mini watermelon will appear in front of your eyes. After a while, when the surrounding is very quiet, it will quietly poke its head out. If it feels safe, it will run away as fast as it can.

We hesitated for a moment, looked around, and piled up tree branches and old leaves to make a barrier. The watermelon bugs were very clever and always found a new way out.

The watermelon bugs make school life more enjoyable!

Watermelon Bugs Observation Diary Part 12

Today, my good friend Wu Qicen and I agreed to go to catch some watermelon bugs at noon to observe them. Watermelon bugs, also known as "women mice", only the size of a soybean, oval, its head with a pair of antennae, gray body, the back of an armor, and a row of small lines. When you touch it with your hand, it immediately shrinks into a small ball, like a pocket watermelon! This is probably the origin of its name! At noon, we took a few small bottles and happily went to catch watermelon bugs. After arriving at the park's octagonal pavilion, we split up and began to look for the target, I chose a piece of wet grass, took out a small shovel and dug hard.

In a short while, I dug a soft hole, and a few big watermelon bugs crawled out of it. I grabbed them in my hand as soon as I could and put them in a bottle. I went back to the octagonal pavilion, and I waited for half a day without seeing him, so I went to look for him and found him lying on a piece of concrete looking for watermelon worms. I cried and laughed and said to him, "Watermelon bugs don't go on concrete, he likes to be in the damp dirt." Next we chose several places, but there was no sign of worms, but Wu Qicen was not discouraged at all, and finally with our **** same efforts, we finally caught two big black watermelon worms too. Through the fun of catching watermelon bugs, we also learned that watermelon bugs like to live in dark, moist and soft soil or under small stone slabs, and usually make their nests 1-3 centimeters above the ground. Watermelon bug is really an interesting insect, next time we will come together to observe it!

Watermelon Bug Observation Diary Part 13

(a)

Under the flower bed in the northwest corner of the campus, there is a small hole, not too big, not too small, ring-shaped.

It carries a small, black and unattractive "pot" and enters the hole.

After a while, it came out, and the burden had been removed, revealing a small watermelon-like shell. It crawled very slowly, wall to wall, seemingly at leisure, strolling.

(2)

I stretched out a finger and gently touched it, and it immediately curled up, and the folded nodes on its back were quickly pulled apart, and it curled up into a watermelon, and did not move.

A few minutes later, it moved a little bit, after probing around the danger has long been gone, it let go of the body, many small feet scramble to step, seems to return to the ring-sized cave, the look and yesterday's leisurely, has been very different.

(3)

Mischievous me, find a twig, a hard to the small hole. After a while, the watermelon bug came out of the hole with a crooked "small step".

It climbed up the rock wall to the flowerbed. When it reached the edge of the flowerbed and the grass, it hesitated for a moment. However, it quickly turned over, laying on its back on the soft soil, and then a carp, burrowed into a dead leaf, and disappeared.

When I looked back, I was surprised to find that the leaf had been gnawed by a small watermelon bug, which was strolling out from underneath.

(4)

I'm at it again. I drove the watermelon bug out of its little hole. It looked at me timidly and ran away again with its body on its thin little legs.

I found a few leaves, torn in a hurry, and stuffed them into the hole with a twig, then filled it with some soil, flattened it, and sat down to wait.

In a few moments it returned.

He saw his home, but he did not go in, but went on as if he thought it was no longer his home, or as if he thought his home was still ahead of him.

It walked half a meter away, stopped, turned around, and went back to the side of the little hole.

(v)

It didn't have the big knife of a praying mantis or the big pincers of a crab, so it had to use its own body to arch out the soil and leaves. It rushed up with its little feet spread wide and stomped on the earth with its feet, pushing too hard and tipping itself over. For a while, it struggled to get up, and gently brushed the hole with its feet, and quite a lot of soil fell down, the largest piece was as big as a jasmine bud. This is much better, it slowly climbed into the bud-sized position, continue to brush the soil inside the hole.

The hole was dark and backlit, so I couldn't see what it was doing in there and how it was progressing; all I could see was that there was a small, grayish-black figure working away in there, pushing out some dirt from time to time.

Watermelon Bug Observation Diary Part 14

In the afternoon, Li Meng Han mysteriously pulled me to the corner and stretched out a hand with a paper-folded box in it, "Look! What's this?"

I saw an oval, slightly flattened gray-brown bug in the box at once: "Watermelon bug. Where did you find that? However, its body is a bit curved, so it should be old."

Li Meng Han did not answer my question, but just asked me to keep an eye on the watermelon bugs, so as not to let the "fruits of their labor" escape.

I picked up the watermelon bug and put it in my hand.

I picked up the watermelon bug and put it in my hand. It immediately stretched out and spread its body after stopping, and its claws were flailing, which almost scared me.

After counting, I realized that it has six pairs of feet, eight segments, and two antennae that are slightly longer than the feet.

However, it does not seem to have eyes, crawling two tentacles straight swing, explore the road before going, and he also likes to drill holes, whether it is a paper hole or a hole in the earth, as long as it can be found, it will have no choice but to drill in.

I think this may have something to do with its habit of liking dark and wet places.

I must say it is a very interesting object of observation.
