An interesting fact about grasshoppers is that of the over 10,000 species of grasshopper, close to 400 species inhabit western North America, and of these 70 are considered common. Many are considered pests and can migrate thousands of miles wreaking havoc on crops. Others, however, are beneficial and actually aid in the control of pests.
An interesting fact about grasshoppers is that their life cycle is incomplete: egg, nymph, adult – skipping the larvae stage. The female deposits her eggs in the soil and then covers them. Over time and depending on the weather conditions and species, immature nymphs develop, emerge from the eggs and soil and begin their metamorphosis. The nymphs undergo anywhere from three to six instars until they are fully mature adult hoppers. 
Grasshoppers Daily Activity
The grasshoppers will seek cover at night sometimes burrowing into the ground for warmth. They are immobile at dawn and only begin stirring when the sun warms them sufficiently – usually around 10:00 AM. They will then bask in the sun, positioning their bodies to maximize the heat of the suns rays. They will soon begin to feed or look for a mate; however, an interesting fact about grasshoppers is that they cannot fly until the ground temperature reaches well above 60 degrees F.
Often a grasshopper in flight is accompanied by a clicking sound called crepitation, caused by the rapid flexing of its wings. Hoppers communicate in this way as well as through sight, often exposing their abdomens or underside of their wings in warning or, in the female case, to attract a mate.
A Matter of Fact About Grasshoppers Reproduction:
Courtship is conducted on the ground and another fact about grasshoppers is the male can detect a female from a distance of at least two feet away. He runs at the female a number of times only to pause and take a moment to stridulate . Stridulation is kind of a mating call. The male hopper emits a noise by rubbing its hind legs against its abdomen or tegmina (the hardened or leathery forewing). The chirping you hear when streamside casting a fly is actually a couple of hoppers getting ready to copulate.
The male hopper approaches to within 1-inch of the female and orients her face-to-face. They wave their antennae at each other while the male continues to chirp. Next the male moves to the female's side, then faces and sometimes butts her thorax. The male continues chirping delightedly as he mounts the female from the rear and, if accepted, the pair begins their amorous dance. In one successful pairing the couple were observed to be engaged for close to 30 minutes. 
One last fact about grasshoppers is that depending on the species the female will carry her eggs for up to 45 days until she deposits them. She deposits them in pods of up to 20 eggs. In some species, males will accompany the females until the eggs are laid, whereupon, a male will immediately begin the courtship ritual again – no rest for the weary.
