Egg to nymph
Grasshoppers undergo simple metamorphosis
Egg are oval, the size of kernels of rice
Eggs may be white, yellow-green, tan, or various shades of brown
Eggs hatch into nymphs, which look like little adults without wings or reproductive organs
Metamorphosis of the nymph
Newly hatched nymphs are white
With exposure to sunlight they assume distinctive color and markings of adults
Picture shows six stages of development from small wingless nymph to fully grown winged adult
Grasshoppers do not take care of their young once they have hatched
Grasshoppers in popular culture
“The ant and the grasshopper”, written by Aesop (620-560 BC)
In “Poprygunya” written by Chekhov in 1892 an unfaithful woman (hopping from man to man) was known as a grasshopper.
Later those who were unable to focus on a single subject (hopping from one thing to another) was said to have a grasshopper’s mind.
Recently, (1972-1975) in the T.V. show Kung Fu, the trainee, who had much to learn, was called grasshopper.
In the 1998 movie, “A Bug’s Life” the heroes are members of an ant colony, and the villain is, who else, the grasshopper.
