Study Notes

Insect Classification

  • Grasshoppers belong to the order Orthoptera
  • Mosquitoes belong to the order Diptera
  • Cockroaches belong to the order Blattodea
  • Houseflies belong to the order Diptera
  • Butterflies belong to the order Lepidoptera
  • Honey Bees belong to the order Hymenoptera

Insect Biology

  • Ecdysis is the process of periodic shedding of the exoskeleton in arthropods to allow for growth and metamorphosis
  • The integument is the external covering of the body in insects, which is ectodermal in origin and varies in rigidity and flexibility

Cuticular Appendages

  • Examples of cuticular appendages include spur and spine, wax gland and mealy bug, scales and bristles, and glandular seta and sensory setae.

Insect Integument

  • The insect integument consists of three main components.

Insect Anatomy

  • The epidermis is referred to as the "Inner of Insect".

Molting Process

  • The physical limits of the exoskeleton trigger the process of molting in insects.
  • The term ecdysis refers to the separation of the old exoskeleton from the epidermis during the molting process.
  • Apolysis is a related process that occurs during molting.
