Insects are like arthropods because they have a segmented body, an exoskeleton, and jointed appendages They have a body divided into three parts: the head, Thorax, and abdomen Three pairs of legs are attached to the thorax
3
Insects, centipedes, and millipedes are all Uniramians It is the group that contain more species than all other groups of animals alive today Uniramians have jaws, one pair of antennae, and unbranched appendages They all have very different life styles
4
They have more than 100 pairs of legs, depending on the species. They are carnivores whose mouths include a pair of venomous claws. Centipedes usually live beneath rocks or in the soil, theses centipedes loose water fast because of their spiracles cannot close, therefore they cannot live in most humid areas.
6
have a highly segmented body but each millipede can bear two legs instead of one ( diego talk’s) They live near dead logs and under rocks because they feed on dead plants. if threatened they will roll up to a ball to protect themselves. Some of them can release toxic chemicals when they feel in danger
8
Insects use a multiple set of sense organs on a everyday basis (eyes, taste, ears, touch, and smell)for example: They have compound eyes that are made up of many lenses to detect change in movement and changes of color. They see less detailed than us but they detect movement really fast therefore its hard to swat a fly.
9
They have chemical receptors for taste and smell on their mouth parts They also have it on their antenna and legs so if they step on water it knows if it is made up of salt or if it contains sugar They also have sensory hairs that detect movement when they fly or in water Use saliva to break down their food
10
they have very developed ears to hear sounds far above the human range People think that bugs do not have ears because they cannot see it but most insects hear better then humans do.
11
Insects have three pairs of legs which depending on its species can be used to help for walking, jumping or capturing its prey. They have hooks that are used for grasping and defense.
12
These insects grow and developed through a cycle called metamorphosis (Lester talks) insects hatch nothing like their parents and feed completely different ways than adult insects. The larva forms into a pupa where the body is completely different and when it emerges it looks like another animal. Example (butterflies)
14
The cocoon hatches and turns the larva into a complete different animal. Example the butterfly which is the most common insects fly depending on their species cause some fly slow like butterflies or fast like flies or bees that can change their position and speed really fast. A dragonfly can also reach speeds as fast as 50 kilometers an hour! This is the circle of life for bugs.
