Crickets are good luck.

Cricket:
Crickets, family Gryllidae (also known as "true crickets"), are insects somewhat related to grasshoppers and more closely related to katydids or bush crickets (order Orthoptera). They have somewhat flattened bodies and long antennae.

Crickets are known for their chirp (which only male crickets can do; male wings have ridges that act like a "comb and file" instrument). The left forewing has a rib(modified vein) which bears a number of minute teeth. They chirp by rubbing their left forewing against the hind edge of the right forwing. This sound producing action is (called "stridulation"), and the song is species-specific. There are two types of cricket songs: a calling song and a courting song. The calling song attracts females and repels other males, and is fairly loud. The courting song is used when a female cricket is near, and is a very quiet song. Female crickets have a long needlelike egg-laying organ (ovipositor).

Crickets chirp at different rates depending both on their species and the temperature of their environment. Most species chirp at higher rates the higher the temperature is (approx. 60 chirps a minute at 13ºC in one common species; each species has its own rate). The relationship between temperature and the rate of chirping is known as Dolbear's Law.

Worldwide there are about 900 known species of crickets. Crickets tend to be nocturnal and are often confused with grasshoppers (which are related, but not the same), because they have a similar body structure including jumping hind legs.

In 1970, Dr. William H. Cade discovered that the parasitic tachinid fly Ormia ochracea is attracted to the song of the male cricket, and uses it to locate the male in order to deposit her larvae on him. It was the first example of a natural enemy that locates its host or prey using the mating signal. Since then, many species of crickets have been found to be carrying the same parasitic fly, or related species.

It is also common to have them as caged pets in some European countries, at least in the Iberian Peninsula. Cricket fighting as a blood sport has also been popular, particularly in Macao.

They may be eaten in some cultures and are popular as live food for carnivorous pets.

Grasshopper:
Grasshoppers are herbivorous insects of the suborder Caelifera in the order Orthoptera. To distinguish them from bush crickets or katydids, they are sometimes referred to as short-horned grasshoppers. Species that change colour and behaviour at high population densities are called locusts.

A cricket is an insect with long back legs used for jumping. Many may confuse a grasshopper as a cricket or vice versa because their appearances are very similar. The way to distinguish between the two is crickets have longer antennas than grasshoppers. A cricket's antenna is usually as long as their abdomen or longer. Underneath the wing covers are modified wings. They are so modified that the cricket cannot fly. Instead it scrambles and hops about in long grass. The bristles on their legs help them to grip the long grass to scurry away from predators. Male crickets ears look like a single white dot near the bend of each front leg near the elbow. This is why they are thought to listen with their elbows. The body consists of three parts: the head, thorax, and abdomen.

Crickets are mostly active at night and grasshoppers are active in the day. Crickets use their song to communicate in order to find females and warn off other males. Grasshoppers call in the day also but tend to be located high in the vegetation to see and be seen by other grasshoppers. Grasshoppers blend into the grass, but they also often have brightly colored under wings that they flash when they do this. Crickets then to be dark to blend into the shadows or a re pale green or brown to blend into the vegetation. The wings of a cricket are either absent or atrophied and they don't fly. Crickets also have longer antennae than grasshoppers. The ears of a cricket are located in its legs and grasshopper's are in its abdomen.

Grasshoppers hop in the grass while crickets play some strange game resembling baseball. Plus they are entirely different creatures.

You can see photos of Macro Cricket and Macro Grasshopper on this page: http://raym.deds.nl/insect_pictures.html (click photos to enlarge). Notice that the grasshopper appears to have "knees" ~ the better to hop from place to place.

The grasshopper hops the grass and the cricket cricks. The grasshopper does not crick, and the cricket does not hop grass.

Grasshoppers are green and you usually see them during he day but crickets are night time creatures that are black.

Crickets are annoying and grasshoppers won't die no matter how many times you step on them.

Size and coloration. Also, grasshoppers can fly short distances.
