Objectives: • This lecture gives knowledge about the largest animal group (order Coleoptera), beetles. • Their classifications and identification keys. • Focusing on the most common and important families of beetles. • Butterflies and moths (order Lepdoptera). Their classifications and identification keys. • Focusing on the most common and important families of moths and butterflies.Scientific content:- Order Coleoptera General descriptions Classification: Suborder: Polyphaga Order Lepidoptera General descriptions Classification: Butterfly families and Moth families
  3. 3. Order: Coleoptera• Fore-wings modified to elytra and hindwings are membranous.• Chewing mouth parts,• Different kinds of antennae• No Cerci• Mostly terrestrial and some aquatic• Larvae (Campodieform or Scarabieform) with a distinct head and biting (chewing) mouthparts, with or without thoracic legs, only rarely with prolegs.• The pupae of beetles are either with legs tightly pressed against the body, or exarate, with the legs and wings held free from the body.
  4. 4. Suborder: Polyphaga• Family: MELOIDAE (blister beetle) Mylabris sp.• Family: SCARABAEIDAE Adults may be recognized by the lamellate terminal segments of their antennae. (Rhinoceros beetles) (Dung beetle)• Family: TENEBRIONIDAE (darkling beetles) (Tribolium spp.),• Family: COCCINELLIDAE (ladybugs, ladybird beetles) Coccinella septempenctata
