Why do katydids chirp so happily at night?

The reasons why katydids chirp so happily at night are as follows:

1. It may be for the purpose of courtship. There is a mirror-like sound-making structure under the wings of male katydids. When the upper wing rubs against the mirror of the lower wing, it vibrates and makes a sound, thus generating courtship information to attract females.

2. It may also be because the temperature is lower at night. Experiments have shown that when the temperature is lower, the number of times katydids chirp will increase.

What do katydids eat?

Grasshoppers feed on fresh red dates, sweet potatoes, and carrots, but the food must be fresh, otherwise they will not eat. Grasshoppers also have a special feeding habit, that is, food diversification. After eating one kind of food, if you change it to another kind of fresh food, it can still eat some. If you change it several times in a row, it will not be full, even if its stomach is big, it will not be bloated to death. In addition, it will not starve to death if it is not given food for a few days. It is particularly resistant to hunger.

Can katydids fly?

The katydid can fly short distances. The body of the katydid is flat or cylindrical, the antennae are generally longer than the body, and the wings are developed or underdeveloped or absent. Male winged individuals have a sound organ near the front wings, which produces sound by rubbing the left and right wings together. The katydid has a well-developed jumping hind leg. When in danger, they can quickly jump to avoid the enemy and fly short distances as a way to protect themselves.
