Re: What is the difference between acricket and a grasshopper?

Oooo, you asked a question dear to my heart! There are a few. For one 
crickets are mostly nocturnal (active at night) and grasshoppers are 
diurnal (active in the day). Because of this, 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.  So grasshopper have really good eyes.  
Grasshoppers blend into the grass, but they also often have brightly colored 
under wings that they flash when they make short flights from place to place 
and also make noise when they do this. Crickets then to be dark to blend 
into the shadows or are pale green or brown to blend into the vegetation. So 
the time of activity and the method of communications is the answer.  Other 
differences are anatomical (body differences) and taxonomic (insect 
classification) more information can be found under cricket links:
