Do Crickets Have Eyes and Ears?

Crickets have two compound eyes behind on their long antennae which have lenses to protect them from their predators. They have ears on legs.

They also have three simple eyes on their forehead and these eyes are called ocelli.

They are known to have excellent eyesight and their eyes are known as compound eyes that are made up of a large number of lenses that are so small or miniature to help them see what is in front of them.

Unlike their compound eyes, these ocelli have a single lens that will help them in distinguishing light and darkness which is one of the interesting facts about crickets.

Do They Have Ears?

Their ears are located on their front legs and are a sound receiver having four acoustic inputs. In their right ear, one input is the eardrum external surface. Sound will propagate from the ipsilateral spiracle through the acoustic trachea to the inner surface of the eardrum.

The sound from the CS or contralateral space and the contralateral ear will reach the inner part of the eardrum by propagating through the acoustic trachea and transverse trachea. They can hear the chirp of each other through the use of an auditory special organ that is located on their forelegs.

Those crickets that eat parasitic flies have their ears below their neck and head. Their ears are just tiny spots a fraction of millimeters long located on the front of their legs and just below their knees. They are one of the animals that have the smallest ears but are highly sensitive.

Do They Like Light?

One of the three reasons why crickets are attracted to the human property is the light. The light during nighttime is what attracts most crickets. Scientists are not sure why many of these nocturnal insects are attractive toward sources of light. This simply means that bright lights or outdoor lights that are visible through the window will mostly attract them.

They jump, regrow limbs, have eyes and ears, are not harmful. They do not bite, you can eat them, they do not smell. You can silence the chirp.
