In the wild, they found many kinds of insects, from initial fear to approach, and then to step by step interest, realizing their desire to be "small entomologists."
Entomology is knowledge that children have never been exposed to in their lives. The big reason is that there is no chance to see the animals in the zoo in the city, but there are few insects. In Dabao's words: "The field is really a paradise for big insects!" We found five kinds of insects in the autumn harvest.
The first kind: ladybugs
Type: beneficial insect
Species: COLEOPTERA insects
Appearance: the general name of the round beetle is a small insect with bright colors and often red, black or yellow spots.
Nicknames: Xiao Pang, Hong Niang, Hua Dajie (referring to the 28-star ladybug, which is a pest), scarab, and even some species have an unpleasant smell because of their secretions, commonly known as smelly turtles (but this is also a mixed name).
Details: Looking at the ladybug that landed on the corn pile, my sister shouted excitedly, "I know, it's called ladybug, and I drew it in art class." After observing for a while, he asked his younger brother, "Shouldn't ladybugs have seven points?" Why so many? "When I heard this question, my brother was shocked. Obviously, the pictures in the book don't give the answer.
Ask his father at once. Mr. Wang is now a "living encyclopedia" in the hearts of children. He explained: "there are several points on the back of ladybugs that will be called ladybugs." Because ladybugs are most famous for eating aphids and protecting crops, they are collectively called ladybugs. But all ladybugs eat pests and protect crops. "
Hearing this, the younger brother said to his sister, "We should also protect ladybugs. They are good insects. " .
The second kind: mantis
Type: beneficial insect
Species: mantodea Insects, Insecta, Arthropoda.
Appearance: Mantis is characterized by its green body and a pair of sickle-shaped grasping feet on its chest, which can be folded to catch food. The head is triangular and flexible. Compound eyes are relatively large, on both sides of the head. Its abdomen is bigger.
Nickname: knife beetle, invertebrate
Details: Mantis looks a little scary, but it is the natural enemy of many insects. They can kill more than 40 kinds of pests, such as flies, mosquitoes, locusts, moths, butterflies and their larvae, small insects such as naked pupae and crickets, and large insects such as cicadas, locusts and owls.
My brother looked at my bag bitten by mosquitoes and prepared to catch a mantis and go back to eat mosquitoes. I seem to watch my family jump out of mantis at any time. This love is too deep!
The third kind: dragonfly
Type: beneficial insect
Species: Heteroptera insects
Appearance: the base of the rear wing is slightly larger than that of the front wing, and the wing veins are slightly different. When resting, spread your wings and lay them flat on your sides. Larvae is short and thick, with rectal gills and no tail gills.
Details: Seeing dragonflies flying by, my brother immediately recited an ancient poem: "Xiao He only showed sharp horns, and there were dragonflies standing on his head. Doesn't it only live by the water? " Why are you flying in the field? . "
Grandpa smiled and said, "Dragonflies are not only experts in catching insects in the field, but also' meteorologists'".
"Why?" The curiosity of brothers and sisters was hooked up.
"There is a good saying: Dragonflies fly low, and when it rains, there is no wind. There is wet moisture in the air before it rains. Dragonflies fly very low in order not to get their wings wet. Therefore, as long as you see the dragonfly flying very low, it means it will be windy and rainy. " Grandpa patiently explained to the children.
The fourth kind: crickets
Type: Pest
Species: Insecta Orthoptera Cricket Family
Appearance: Crickets are more than 3 cm long; Body color varies greatly, mostly from brown to dark brown, or green and yellow. Round head, wide chest and slender tentacles. Chewing mouthparts. Some jaws are developed, which is worse than biting a bucket.
Nicknames: promoting weaving, commonly known as cricket, nocturnal insect (because it chirps at night), common insect, autumn insect, cockfighting, promoting weaving, ground horn, kitchen chicken, Sun Wang, soil thorn and "monk" are the names of cricket before it gives birth to wings.
Details: In order to let the children get close contact with crickets, Mr. Wang brought two back with his younger brother. Cricket is an ancient insect with a history of10.40 billion years, and it is still the object of struggle between ancient and modern times. I always thought that the purpose of dad catching crickets at home was to beat crickets. At night, two crickets will make a "chirp" sound. This coke broke two little guys and followed them around the cricket.
Although crickets can "sing" and tease, they are big pests that harm crops. They destroy the roots, stems, leaves, fruits and seeds of various crops, especially seedlings.
In South China, crickets harm peanut seedlings by up to 1 1% 30%, and also harm corn, jute, tobacco, cotton, soybean and cassava, often causing seedling shortage and affecting harvest.
Fifth species: locusts
Type: Pest
Species: ORTHOPTERA Acridoidea
Nickname: grasshopper
Details: Apart from crickets, locusts are the most common jumping insects in the field. My brother watched the locust jump at his feet and caught it without hesitation. My grandfather told him, "This locust is a pest, and many leaves of crops have been eaten by this insect." Hearing this, my brother immediately decided to take this locust back to study with crickets.
During this short holiday, the two of them had a good time and learned a lot. I really think I made the right decision to take them to work in the fields. Where can children in the city experience so many interesting insects for themselves?
Pillow parenting information:
There are more than five kinds of insects in the field, just a few that children can see and accept. But this discovery is enough for them to have a preliminary understanding and interest in entomology, and I hope they can find more in the future. Do you have the urge to take your children to nature?
