"Locusts are part of a large group of insects commonly called grasshoppers which have big hind legs for jumping. Locusts belong to the family called Acrididae [,short-horned grasshoppers]. Locusts differ from grasshoppers in that they have the ability to change their behaviour and habits and can migrate over large distances. As Desert Locusts increase in number and become more crowded, they change their behavior from that of acting as an individual (solitarious) insect to that as acting as part of a group (gregarious). The appearance of the locust also changes: solitary adults are brown whereas gregarious adults are pink (immature) and yellow (mature). Up until 1921, it was thought that the Desert Locust was actually two different species of locusts." http://www.fao.org/ag/locusts/en/info/info/faq/
if it is flying ,it is a mature cockroach if it not flying it may be a mature cockroaches or a nymph (immature)
A baby cockroach looks like a cockroach but smaller. a baby butterfly is a caterpillar.
The difference between a locust and a katydid is a locust is short horned grasshopper. A katydid is a long horned grasshopper, or what is known as just a grasshopper.
Swarming locust is a locust that is flying in a huge group of other locusts. They generally take over and consume everything in their path. A crawling locust is solitary.
There is no difference. A water bug is a type of cockroach. It is different from the more common American Cockroach, which is why some people claim it is not a roach.
locust are a lot bigger than crickets
A caterpillar has more than six legs while a cockroach nymph has six legs
well the legs of the cockroaches are small compared to the grasshoppers and grasshoppers have strong legs compared to cockroach.
The German cockroach is a bit smaller, and slightly faster. The American cockroaches are the largest cockroach that tends to inhabit homes. The German has the highest reproductive rate of the two.
The Dragon Fly is the fastest insect. The fastest insect on the ground is the cockroach.
i think that one is big and one is small
NOTHING! "Roach" Is just another (probably informal) term for cockroach. Just like soap operas are often called "soaps".
