Grasshopper is an insect which belongs to the order Orthoptera. There are more than 11,000 species of grasshoppers which can be found around the world, with the exception of Antarctica. They can survive in numerous habitat and different climates. They can be found in tropical forests, temperate forests, rocky areas, and meadows, areas near the streams and ponds, and even deserts. Grasshopper is symbol of good luck in Japanese Culture. Some species of grasshoppers are currently endangered due to loss of habitat (as a result of increased urban development and agriculture).
Grasshopper densities vary every year based on numerous environmental factors, like moisture, temperature, and forage availability. In an ordinary year, densities of eight grasshoppers per square yard are very common. In years when outbreaks happen, densities may easily reach more than 60 grasshoppers per square yard. Managers normally consider an economic threshold density when determining whether to treat a grasshopper outbreak. An economic threshold refers to the density at which the cost of the destruction will be higher than the cost of treatment. Previous research indicates grasshopper suppression treatments are usually warranted when densities go beyond 15 grasshoppers per square yard.
Grasshoppers are both adored characters in the stories of children and despised pests which often plague ranchers and farmers. Their songs contribute to the exceptional summer’s soundtrack. Even though grasshoppers are among the insects we encounter almost each day, many people know very little about them.
Learn more about these amazing creatures, beginning with these ten facts about grasshoppers.
1. The size of grasshopper usually depends on the species. Smallest grasshoppers are just 0.5 inches long. Larger species can grow even up to five inches in length. Females are longer than males.
2. The color of the body offers to camouflage, and it depends on the habit. Grasshopper can be brown, green, ochre and grayish in color.
3. Grasshoppers have one pair of antennas on the head. They serve as the quick sensory organ that detects different stimuli from the environment.
4. Grasshopper also has an eardrum on the abdomen. Grasshopper can detect intensity and rhythm, but it can’t hear the pitch of a sound.
5. Grasshopper has long hind legs which are designed for jumping. String-like structure acts like a catapult that sends grasshopper ten inches high in the air. An adult grasshopper is capable of leaping 20 times its length horizontally and ten times its length straight into the air. If a man had similar abilities, he could jump over a 5-story building and clear a football field in just three leaps
6. Front legs of grasshopper are shorter than hind legs. They are used for feeding and walking.
7. Grasshoppers have wings which are used for flying. Grasshoppers usually gather in bigger groups (then they are called locusts), which migrate together toward the better food sources.
8. Grasshoppers are always active during the day (diurnal creatures). They require increasing their body temperature with the assistance of sun before they become ready to kick-off the day.
9. Some grasshopper’s species can spit a brown, bitter liquid as a defensive behavior when they are touched. This liquid is usually known as “tobacco juice.”
10. Do you know that grasshoppers often sing late at night? If you did not sleep the whole night and suddenly wake up and you will hear the chirping voice emerging from the deep darkness, it would be the grasshoppers singing voice. They don’t sing for us; rather the main purpose is to attract females toward them for mating.
