Species
✓ Groups of plants or animals that look-alike with similar characteristics and living
traits
Hexapoda
✓ The Class that all insects belong to, formally "insecta"
Chordata
✓ The most familiar Phylum that includes the mammals, birds, reptiles and fish
"vertebrate pests"
Mollusca
✓ Phylum that includes snails, clams, etc. These are also tiny organisms, almost
too small to be seen with the naked eye, called protozoa.
Arthropoda
✓ largest phylum by far that contains the largest class,"Hexapoda". no one feature
alone will separate the Arthropoda from all other animals. Segmented bodies,
jointed appendages, shell like body "exoskeleton". They also have bilateral
symmetry. (Each side of the body is the same as the other)
Crustacea
Top Mark !!!
, Top Mark Questions and Correct Verified Answers
✓ water inhabiting animals which breath either by gills or through the surface of
their bodies. Numerous pairs of legs; two pairs of antennae, fused head to the
body. Lobster, crawfish, crab, sowbug & pillbug
Diplopoda
✓ Land animals which breath through air tubes on the side of their bodies. one pair
of antennae, cylindrical bodies with a series of segments which look very much
alike. each segment has two pairs of legs. "Millipedes"
Chilopoda
✓ Have antennae and breath by air tubes. body is more flattened and each
segment bears only one pair of legs. "centipedes"
Hexapoda
✓ INSECTS: have three distinct body regions. The head, the thorax and the
abdomen. they have only one pair of antennae, six legs that are all attached to
the thorax. usually four wings if they have them that are also attached to the
thorax. "Air tubes"
Arachnida
✓ Have only two body regions, The cephalothorax and the abdomen. they do not
have antennae and the cephalothorax bears eight legs. they breath with book
lungs. Some smaller arachnids breath through surfaces on the body.

✓ 3. three body regions
✓ 4. exoskeleton
✓ 5. three pairs of jointed legs
✓ 6. one pair of antennae
✓ 7. two pairs of wings, usually
✓ 8. airs tubes for breathing
Ametabola (No Metamorphosis)
✓ group said to have no metamorphosis. "Silverfish and springtails"
Heterometabola (Gradual Metamorphosis)
✓ there is some change in the insect as it grows up other than merely a change in
size. development of wings as the insect gets larger.
✓
✓ Life Stages: Egg, Nymph, Adult
✓ (Roaches, grasshoppers, bedbugs, termites, stink bugs)
Holometabola (Complete Metamorphosis)
✓ insects that have four distinct life stages. Usually the larvae live on entirely
different food and do not resemble the adults.
✓
✓ Egg, larva, pupa, adult.
✓
✓ Beetles, fleas, flies, ants, bees, weevils.
Molting
Top Mark !!!
, Top Mark Questions and Correct Verified Answers
✓ the cells of the exoskeleton called the hypodermis secretes a molting fluid which
separates the insect allowing the insect to slide out of the shell and grow by
filling itself with air or water.
Instar
✓ 1st, 2nd, 3rd Instar describes the stage at which the size of the insect will
represent which molt age they are currently at.
Chitin
✓ Chitin is the substance produced by the hypodermis that eventually hardens and
becomes the new exoskeleton
Compound Eyes & Ocelli
✓ Compound eyes are the larger and most visible eyes (Fly) while Ocelli are much
smaller and vary in number but usually contain only three
Labrum
✓ flap like upper lip which is hinged and moves back and forth. It covers the upper
part of the mouth
Mandibles
✓ are powerful jaws that move in and out from each side masticating the food.
Maxillae
✓ secondary smaller jaws that hold the food while the mandibles break it up
