Flying Insects Insects are the most successful animal on earth, and their ability to fly is a large contributor to this fact. Flying allows them to travel great distances in relatively short time intervals. Finding food, mates and favorable habitats as well as avoiding predation are some advantages of flying. It may sound easy to describe how insects fly, however it really is not easy at all. The reason for this is virtually everything about how they accomplish flight is species specific! A few characteristics shared by flying insects are as follows: proper muscles in the right places, the structure of the skeleton the muscles are attached to which enable a large amount of wing movement with a small change of muscle length, and the ability to control direction while flying. In addition to this, their ability to fly is temperature dependent. If the body temperature is to low sleight muscle contractions in the thorax will raise it up enabling maximum efficiency of muscle contractions. Finally and most important, all flying insects must have wings ( Pechenik, 1996 ).
