How did locusts gather into hundreds of billions in such a short time?

Locusts can reach a huge number of hundreds of billions in a short time, which is mainly caused by the local climate and the super reproductive ability of locusts. An old saying? A plague of locusts occurred after the drought? When the land is dry to a certain extent, it is very suitable for locusts to lay eggs in large quantities. Locusts will lay eggs in a large number in selected specific areas, and even hundreds of thousands of locust eggs can be laid per square meter on land with suitable humidity. After 20 days, these eggs will hatch into locusts, and it is not surprising that hundreds of billions of locusts will gather in some arid areas.

Grasshoppers are very cowhide. Locusts are what we call grasshoppers in rural areas. This is an animal that looks very small, but it is actually very powerful. First of all, their hind feet are very strong, and there are sharp serrated spikes on their legs, which can easily prick people's fingers and bleed; Secondly, their mouthparts are very sharp and powerful, and they can eat animals' bodies and various crops and vegetation. They are omnivorous animals and can eat anything, so they have caused great damage to crops and plants in history, and even there are records of attacking humans in ancient books. Once they gather more and form a scale, it will pose a great threat to the survival of mankind; In addition, their wings are very developed and they can fly a long distance before landing. Humans can't catch up with them at all, and it's not easy to kill them.

Locusts have a strong reproductive ability. Each female locust can lay 50 ~ 100 eggs at a time, and the eggs will hatch into small locusts after 2 1 day, and the reproductive cycle is very short. Moreover, if the conditions are suitable, female locusts will lay eggs many times, which makes the number of locusts multiply, so the locust population can grow rapidly in a short time.

There is an old saying about the breeding environment of locusts. Drought and locusts? Under the condition of long-term and large-scale drought, it becomes the best feeding and breeding season for locusts, especially the water content in the soil is relatively low, between 10%-20%, which is most suitable for them to lay eggs in the soil. In rivers and lakes with small arid areas, the number of locusts laying eggs is particularly large, and even 200,000 to 400,000 eggs can be laid per square meter of soil.
