Crickets are found in North
America and throughout other parts of the world. There are about 900
species of crickets worldwide.
Crickets are thought to bring good luck in many countries.
They are, indeed, are fascinating creatures. But
do they have ears like humans?
Crickets have many amazing abilities. They can
see in different directions at the same time.
They can even tell you the temperature! Yes, you can
tell the temperature by counting a cricket¡¯s chirps. The higher the temperature,
the more chirps a minute a cricket generates. When the temperature
is 10 degrees, crickets chirp about
60 times a minute.
Crickets
feed on plants and sometimes
other insects. They have a life
span of less than a year. Female crickets do not chirp;
only males do. A male generates the chirp sound when he raises his left forewing
and rubs it against the upper
edge of his right forewing.
So do crickets have ears? Yes, they do! Surprisingly, their ears are
located on the knees of their front legs!
They detect sound through eardrums on their front legs.
Sound passes through a lipid (a compound that includes oils
and fats) to get to the insect¡¯s hearing organs! |
