  1. Collections II: Entomology Diet and Feeding

  2. Three basic types of diets: • saprophytic • phytophagous • carnivorous

  3. Saprophytic • recycle nutrients • Types of food sources: • Plant remains • Animal corpses • Animal feces

  4. Saprophytic examples: Dung beetles recycle animal feces Maggots feeding on animal remains

  5. Phytophagous • consume plants (3 main types): • Polyphagous: (eg grasshoppers) consume many species of plants • Oligophagous: (eg wander butterfly larvae) consume a few species of related plants • Monophagous: (eg citrus butterfly, white cedar moth) consume a single species of plant

  6. Plant-eaters mouthparts: • Chewing - leaves, stems, roots, fruit, wood, flowers, pollen • Piercing/sucking - leaves, roots, stems (either phloem or xylem) or nectar • Sucking or lapping - nectar or sap

  7. Chewing examples: Leaf blisters Sawfly larvae Leaf mines

  8. Piercing/sucking examples: Lerps – protective outercovering of jumping plant lice Spittle Bug

  9. Sucking or lapping examples: Honey Bee Butterfly

  10. Carnivorous • Carnivorous insects (animal tissues): • Predatorseats insects or animals • speed (e.g. robber fly, dragonfly) • trap (antlion larva) • use of modified appendages (e.g. raptorial legs of mantid, extendable labium of dragonfly nymph). • Parasites  live off a host but do not kill it. • Ectoparasites live externally on the host; • Endoparasites live inside the host. • Parasitoids kill the host.

  11. Predator examples: Praying mantis with prey An Ant lion Pit

  12. Parasite example: Mosquito about to feed on blood

  13. Parasitoid example: A tobacco hornworm (Manduca sexta) parasitised by braconid wasp larvae
