Beetles are the group of insects with the largest number of known species. They are members of the largest order of animals: Coleoptera.

  • 25 percent of all life-forms
  • 40 percent of all species of insects are from the beetle family (about 400,000 species)
  • Total species: Some estimates as high as 100 million; 1 million more probable
  • Largest family in the animal kingdom belongs to this order – the weevils or snout beetles

Family Structure

  • Eggs: Each female has several dozen to several thousand over the course of her lifetime
  • Morph after birth into a completely different body structure
    • First stage: larvae. May last several years in some species
    • Second stage: pupa
    • Third stage: adult


  • Body: head, thorax, and abdomen


  • Found in almost all habitats, including freshwater and marine
  • Live wherever vegetative foliage grows – in tree bark, flowers, leaves, underground near roots, inside plant tissue


  • Plants and fungi
  • Break down animal and plant debris
  • Other invertebrates


  • Prey of other animals, including birds and mammals
  • Some are agricultural pests (e.g., boll weevil, red flour beetle, Colorado potato beetle, and cowpea beetle)
  • Others are important to controlling other agricultural pests (i.e., beetles in the family of ladybirds or ladybugs eat other insects that damage crops)
