WHERE DO GRASSHOPERS LAY EGGS

WHERE DO GRASSHOPPERS LAY EGGS?


Every now and then great swarms of grasshoppers have appeared in certain places and devastated the land .They are mentioned in the Bible among the seven plagues of Egypt .But every year ,in most part of the world ,they do thousands of dollars worth of damage to crops. There are many varieties of grasshoppers but they look very much alike .They all have strong jaws, three pairs of legs, and usually have two pairs of wings .The first pair of wing is leathery and straight, while the second pair is membranous and fold underneath the first pair .The hind pair of legs, which are used for jumping are usually long and well developed.

The female grasshopper has an organ for laying eggs at the tip of her abdomen .This organ is called an ovipositor Katydids have long sword-shaped ovipositors. Some locusts poke holes in the ground with their eggs there, and cover them with a gunny substance.
