1, edible. Locust, commonly known as grasshopper, is rich in protein, and its nutrition is equivalent to beef. It tastes fragrant and crisp after frying, which is delicious on earth. Fried grasshoppers have become an indispensable food in food stalls.

2. Since it is edible, why is the plague of ancient locusts so serious? Why didn't the ancients eat "delicious food from heaven" There are two main reasons for this:

(1) locusts are hard to catch. There was no effective means to catch locusts in ancient times. Locusts often fly around in droves and their whereabouts are uncertain. Sometimes they will move dozens of kilometers in one night. Before seeing the shadow of locusts, all the crops in the field were gone, let alone catching locusts to eat.

The heat brought by locusts is too small to meet the needs of human beings in a day. When the locusts passed by, nothing grew and the crops were gone. There will be a terrible famine when the stock runs out. Even if a small number of locusts are caught as "rations" during the locust plague, it is far from enough. It must be "not worth the loss."

So the ancients didn't eat locusts, but when the plague of locusts came, eating locusts could not solve the problem.
