A Grasshopper is an amazing insect that can leap 20 times the length of its own body. If you or I could do that, we would be able to jump almost 40 yards!

What they do is use their legs as a catapult. Grasshoppers can both jump and fly and they can reach a speed of 8 miles per hour when flying.

There are about 18, different species of grasshoppers. Grasshopper Characteristics Grasshoppers are medium to large insects. Adult length is 1 to 7 centimetres, depending on the species. They are different from these groups in having short antennae that do not reach very far back on their bodies. Grasshoppers usually have large eyes, and are coloured to blend into their environment, usually a combination of brown, grey or green.

Grasshopper

In some species the males have bright colours on their wings that they use to attract females. A few species eat toxic plants, and keep the toxins in their bodies for protection. They are brightly coloured to warn predators that they taste bad. Female grasshoppers are larger than the males and have sharp points at the end of their abdomen that are there to help them lay eggs underground. Male grasshoppers sometimes have special structures on their wings that they rub their hind legs on or rub together to make sounds.

Grasshoppers can be found almost everywhere in the world, except for the colder regions near the North and South poles. Types of Grasshopper There are two main groups of grasshoppers: They are designed more for penetration or help in the defensive mechanism they might have.

This usually works with their diurnal roosting posture to maximize defense and prevent predators from going for their head.

This position fools predators into thinking the katydid is either dead or just a leaf on the plant. Various tettigoniids have bright coloration and black apical spots on the inner surfaces of the tegminaand brightly colored hind wings. By flicking their wings open when disturbed, they use the coloration to fool predators into thinking the spots are eyes.

This, in combination with their coloration mimicking leaves, allows them to blend in with their surroundings, but also makes predators unsure which side is the front and which side is the back. The first male to mate is guaranteed an extremely high confidence of paternity when a second male couples at the termination of female sexual refractoriness.

These investment functions are a parental paternity.

The nutrients that the offspring ultimately receive will increase their fitness. The second male to mate with the female at the termination of her refractory period is usually cuckolded. Male competition is caused by the decreased availability of males able to supply nutritious spermaphylanges to the females. Females produce more eggs on a high-quality diet; thus, the female looks for healthier males with a more nutritious spermatophylax.

Females use the sound created by the male to judge his fitness. The louder and more fluent the trill, the higher the fitness of the male. This, however, is a cost to females as they risk predation while searching for males. Also, a cost-benefit tradeoff exists in the size of the spermatophore which the male tettigoniids produce.

Tettigoniidae

When males possess a large spermatophore, they benefit by being more highly selected for by females, but they are only able to mate one to two times during their lifetimes. Inversely, male Tettigoniidae with smaller spermatophores have the benefit of being able to mate two to three times per night, but have lower chances of being selected by females.

Even in times of nutritional stress, male Tettigoniidae continue to invest nutrients within their spermatophores. In some species, the cost of creating the spermatophore is low, but even in those which it is not low, it is still not beneficial to reduce the quality of the spermatophore, as it would lead to lower reproductive selection and success.
