The difference in the cecadas and the locust?

Question

can you tell me what the difference is between the two

Answer 1

A cicada is an insect of the order Hemiptera, suborder Auchenorrhyncha, in the superfamily Cicadoidea, with large eyes wide apart on the head.

Locust is the swarming phase of short-horned grasshoppers of the family Acrididae.

Common name confusion once again illustrating the usefulness of scientific nomenclature!

Cicadas are in the order Homoptera, most closely related to plant lice and leafhoppers.

Cicadas lay eggs in slits in twigs; annual species hatch and mature on their host trees

and sing loudly during hot summer days. Periodical cicadas drop to the ground after

hatching and spend anywhere from a few to 17 years as nymphs feeding on tree roots

underground before maturing to adults. "Locust" is a general, colloquial term that

usually refers to migratory grasshoppers of the order Orthoptera, but is sometimes applied

to other insects of the order, including crickets and katydids.
