tolongsih text tentang crickets

crickets are an insect type animal
crickets have 2 main color green and brown
all crickets have wings
crickets have a saw like long legs
crickets are carnivore and females also eat their mate so i guess they're also kanibals
the seventh question is kinda confusing so ill say that all of them are predators 
by making a cricking sound using their legs by scrubbing them together
for my opinion i think crickets have no use to humans (i'm sorry for if this is wrong)
one of the disadvantages of crickets is the female is a cannibal 
females lays eggs on the leaves(this one im sorry if im wrong
