Why do insects have hairs?

We conclude that ocular hairs act similarly to mammalian eyelashes: as insects fly, ocular hairs deflect incoming air and create a zone of stagnant air. Airflow and particle deposition are reduced dramatically, while light is only minimally occluded.

How does the hair on insects help them?

It captures them and allows them to be eaten. Setae on the integument of insects are unicellular, meaning that each is formed from a single epidermal cell of a type called a trichogen, literally meaning "bristle generator". They are at first hollow and in most forms remain hollow after they have hardened.

Why are spiders scary?

Longer legs were associated with perceived fear as well; however, the presence of two eyes did not produce any statistical significance in terms of fear.

What is the stance phase of an insect?

The stance phase is what pushes the body forwards and the direction that the insect wishes to travel in, while the legs remain on the ground. Three legs will be used in this phase to form a tripod with the front leg and the hind leg on one side of the body and the middle leg on the other side. This is why it is referred to as the tripod gait.

Why does the exoskeleton restrict movement?

As well as this, the exoskeleton will effectively restrict any small bodily movements in order to control balance. Bigger animals, like mammals, will be able to make small and constant adjustments in their gait in order to remain balanced, but an insect will be less able to do so due to its exoskeleton.
