  • 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

    KingdomPhylumClassOrder FamilyGenusSpecies

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

  • 5 Classes of ArthropodsClass #1- Hexapoda: Insects, six, jointed appendagesClass #2- Chilopoda- Centipedes, one pair of legs per body segment, multiple body segmentsClass #3- Diplapoda- Millipedes, two pairs of legs per body segment, multiple body segmentsClass #4- Crustacea- Crayfish, five pairs of jointed appendagesClass #5- Arachnida- Spiders, four pairs of jointed appendages

  • There are 31 different orders of insects in the class Hexapoda, sixteen of which are considered of economic importance to agriculturists. The sixteen orders are:

    OrthopteraHemipteraHomopteraColeopteraLepidopteraDipteraHymenopteraOdonata trevor was hereNeuropteraThysanuraIsopteraSiphonapteraPhthirapteraThysanopteraDermapteraBlattodea
