ADULT
The final stage of metamorphosis for an insect.
ANIMAL
All insects are classified into this kingdom.
ANTENNAE
Organs of touch, taste, smell, and hearing; feelers.
ARTHROPODS
Invertebrates with an exoskeleton and bendable, jointed legs; all insects
CHITIN
Material an exoskeleton is made up of consisting of carbohydrates and protein.
COCOON/CHRYSALIS
Covers a pupa during complete metamorphosis.
COMPLETE
Metamorphosis with four different stages of growth.
COMPOUND
Insect eyes with multiple facets (lenses).
EARDRUM/EARS
The tympanum of an insect is comparable to this human body part.
EGG
Beginning stage of an insect’s life cycle.
ENTOMOLOGIST
A person who studies insects and insect behavior.
EXOSKELETON
The hard covering on the outside of an insect’s body.
HEAD
First body region of an insect which holds the eyes, mouthparts and antennae.
HEMIPTERA
Special group (order) of insects known as true bugs.
INSECTS
The most populous and varied class of organisms in the animal kingdom.
INVERTEBRATE
An animal with no internal structure to support their bodies.
LARVA
Worm-like or caterpillar stage of an insect after it hatches from an egg.
MANDIBLES
Jaw-like mouthparts used for feeding and communicating; snapping mouthparts
MEMBRANEOUS
Clear wings with visible veins such as wasps.
METAMORPHOSIS
The life cycle of an insect.
MOLTING
Several stages of shedding skin; simple metamorphosis.
MOUTHPART
Specially designed body part used for feeding.
NYPMH
A stage during incomplete metamorphosis when the insect doesn’t have wings.
PHEROMONE
Chemical scent insects use to attract a mate.
PROBOSCIS
Long, tube-like mouthpart, that takes up food like a straw.
PUPA
Quiet stage of complete metamorphosis; insects are in a cocoon/chrysalis during this stage

SCALES
Powdery parts of the wings of butterflies and moths.
SHELL-LIKE
Hard, outer wings of insects such as beetles.
SIPHONING
An insect with a proboscis uses this type of mouthpart for feeding.
SPIRACLES
Insect breathing holes.
STRIDULATION
The rubbing of body parts together to make sounds.
THORAX
The middle body region of an insect where the legs and wings are attached.
TYMBALS
Special sound-makers found on the abdomen of cicadas.
Characteristics of all animals in the Class Insecta:
WINGS
6 LEGS
EXOSKELETON
3 BODY PARTS – HEAD, THORAX, ABDOMEN
SIMPLE EYES
COMPOUND EYES
ANTENNAE
JOINTED LEGS
METAMORPHOSIS (EGG-ADULT)
Examples of how insects make sound:
TYMBALS
SPIRACLES
STRIDULATION
SNAP MANDIBLES
TAP BODY PARTS ON GROUND OR WATER
Reasons why insects make sound:
COMMUNICATION
ATTRACT MATES
DEFEND TERRITORY
Positives of insects
MOST ARE NOT HARMFUL TO HUMANS OR
ENVIRONMENT
HELP MAINTAIN NATURE’S BALANCE
POLLINATION
DECOMPOSITION
INTEGRAL PART OF FOOD CHAINS
Negatives of insects
SOME DESTROY CROPS
SOME ARE PARASITES
CAN CARRY DISEASE
Some of the reasons why insects have been on
earth for millions of years and survived in such
large numbers:
INSECTS REPRODUCE RADIPLY AND IN LARGE
NUMBERS
ARE ADAPTED TO LIVE ALMOST ANYWHERE ON
EARTH
CAN HIBERNATE OR MIGRATE TO AVOID HARSH
CONDITIONS
ARE SMALL AND GO EASILY UNDETECTED
EXTREMELY STRONG FOR THEIR SIZE
SCARE PREDATORS
Some of the criteria taxonomists use to classify
insects.
TYPE OF WINGS
WHERE THEY LAY EGGS
TYPE OF METAMORPHOSIS
COLOR
HOW THEIR WINGS FOLD
Important Facts to Know:
Aphids can reproduce asexually.
Flies spit enzymes on their food before they can eat it.
True bugs have long jointed feeding tubes for piercing
and sucking.
Ladybugs are natural predators of aphids
