I suppose it is because the "cricket" sound it makes when it chirps
their legs
They have ears on their "knees" or where they bend their hind legs.
The insect that has ears on its front legs are crickets.
in the front legs
A cricket's ears are on its front legs, just below the knees and they have four acoustic inputs.
for humans its on the sides of the head but for crickets its in their legs and for the grasshoppers its in their stomach!!!
Short horned grasshoppers have ears in the sides of the abdomen. Long-horned grasshoppers & crickets have ears in the knee-joints of their front legs.
The chirp is made by rubbing their left forewing against their right forewing.
Long-horned grasshoppers and crickets have "ears" on their legs. Short-horned grashoppers (the kind seen just about everywhere) are often said to have ears on their legs, but their hearing organ is actually located on the abdomen just behind the rear legs where the legs join the body.
Humans, apes, frogs, dogs, cats, squirrels, etc. I could go on for hours.
yes, crickets have their ears in their knees, so they hear with their legs.
so that they can hear the predetors
