First it should be noted that not all insects have wings or can fly. What follows is the assumption that you mean insects that can fly. The most obvious reason is that flightless predators cannot pursue their prey in the skies. Wings also allow insects (as well as birds) to reach food which may be at a high altitude, such as fruit on a tree. Another huge advantage of flight is the ability to travel…
Insects, such as the praying mantis, do not care for their young. Young insects are strictly on their own, they care for themselves. Since all insect behavior is instinctive, there is actually nothing for young insects to learn from older insects anyway. They are hatched knowing what to do, and they do it.
There are different methods available for protecting trees from insects. Chemical sprays such as insecticidal soaps and horticultural oils as well as trunk or soil injections help killing insects. Though at long term the best way is releasing other insects that feed themselves with the insects you're battling with.
Some plants use thorns to protect themselves from the environment. Some plants, like poison oak, release toxins to protect themselves. Some plants camouflage to hide themselves from predators. Some plants have poisonous fruit. Some plants have tough bark which protects themselves. The redwood tree, for example, has so much tannin in its bark that insects won't eat it. This is why you find very few insects in redwood forests.
All animals and insects cant survive without urinating they have to remove waste! Improved Answer: Actually, stick insects, like all other insects, do not urinate. The waste they do produce is small dark pellets that are dry and ordorless which are called frass. This dry waste helps them conserve water in their bodies to prevent themselves from drying out.
All living species are necessary to the balance of the environment for this or that reason. Take the example of the toads. They feed themselves from insects. If the toads disappear, the insects could proliferate so much making many diseases caused by some of such insects increase all over the world.
