Lesson: Insect Classification
• What is Scientific Classification?
•
Scientific Classification is a system
used to classify all living things
through a breakdown starting with the
largest grouping called a Kingdom and
continuing down to the smallest
grouping called Individual.
• Why is Scientific Classification used in the
identification of insects?
•
•
Insects can be placed into groupings based upon
their physical characteristics. Insects with similar
characteristics, number of wings, mouthparts, etc. are
placed in a group with other insects that possess the
same characteristics.
Identification of insect orders aids in prevention and
management plans.
• Scientific Classification
• Kingdom
• Phylum
• Class
• Order
• Family
• Genus
• Species

Where do Insects fit?
•
Insects belong in the Phylum
Arthropoda. The Phylum Arthropoda
is characterized by having segmented
bodies and jointed appendages.

Class #4- Crustacea- Crayfish, five
pairs of jointed appendages
Class #5- Arachnida- Spiders, four
