1. 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.
