  5. Insects

  6. Chitin – Material that makes up the exoskeleton. Ecdysis – correct term for molting/shedding of exoskeleton

  7. Elytra front wings of beetles modified into wing cover.

  8. Entomology • The study of insects

  9. Haltere – modified 2nd pr of wings in flies.

  10. LarvaFeeding stage in complete metamorphosis.

  11. Instar • Each of the stages between molts.

  12. Malpighian tubules • The excretory structures (“kidneys”) of the insect.

  13. Metamorphosis • “Change in form” during growth. • Complete – • separate stages (larva, pupa) • More advanced • All the most successful orders have complete metamorphosis • Incomplete – young resemble adult

  14. Nymph • Immature stage. Resembles the adult to some extent. A stage in incomplete metamorphosis.

  15. Ovipositor • Egg laying structure (female only) • Becomes sting in bees and wasps

  16. Pheromones • Chemical messages, like hormones but released into the environment. • Lock and key with receptors on the male antenna • 1 mile range!

  17. Pupa • Transformation stage where the larva changes to an adult. • Special terms like cocoon or chrysalis

  18. Spiracles • Openings to the breathing tubes (tracheae) which support respiration in insects.

  19. Tympanum • The “ear” of the insect.

  20. General Insect Characteristics • 3 body parts, head, thorax, abdomen • 6 legs, usually 2 pr. Wings - all from thorax • Exoskeleton of chitin • Breathe by spiracles/tracheae • Wide variety of mouthparts • Complete or incomplete metamorphosis • Estimates as high as 30 million species

  21. Beetles - Coleoptera • Wings - 1st pr. modified into elytra • Allow beetles to go places other insects can’t • Mouthparts - chewing • Metamorphosis - complete - larva often called a grub • Other - largest order • Weevils, scarabs, mealworms, etc.

  22. Beetles - Coleoptera

  23. Butterflies - Lepidoptera • Wings - Scale covered • Mouthparts - Siphoning • Metamorphosis – Complete, larva called caterpillar • Butterflies – wings upright, antenna w/ nobs, narrow body, day active. • Moths – wings fold, feathery antenna, wide body, night active. • Other – a “skipper” has characteristics of both

  24. Butterflies - Lepidoptera

  25. Ants & Bees - Hymenoptera • Wings - 2 pr. Linked, membrane winged • Mouthparts - Chewing • Metamorphosis - Complete • Other - Social, solitary or parasites, 3rd largest • Narrow constriction between thorax and abdomen • Ovipositor modified into sting

  26. Ants & Bees - Hymenoptera

  27. Flies - Diptera • Wings - only 1 pr. 2nd pr - halteres, for balance • Mouthparts - lapping or biting • Metamorphosis - complete, larva are maggots or wigglers (mosquitos) • Other - disease carriers; 4th largest • Gnats, midges, punkies

  28. Flies - Diptera

  29. Dragonflies - Odonata • Wings - 2 pair • Mouthparts - chewing • Metamorphosis - Incomplete, aquatic nymphs, rectal gills, jet propulsion • Other – predators, even as nymphs • Damselflies can fold wings against body, narrow abdomen • Legs form a basket underneath • Fossil dragonflies wingspan, 2 ½ feet.

  30. Dragonflies - Odonata

  31. Grasshoppers - Orthoptera • Wings - 2 pr - straight - 1st leathery • Mouthparts - Chewing • Metamorphosis - Incomplete • Other - roaches, mantids, grasshoppers, walking sticks, etc.

  32. Grasshoppers - Orthoptera

  33. Termites - Isoptera • Wings - 2 pr. Straight if present • Mouthparts - chewing • Metamorphosis - Incomplete • Other - All social, flagellates are symbiotic • Castes include soldiers; 5,000,000 in a colony; huge part of tropical ecosystems; queen might live 50 years

  34. Termites - Isoptera

  35. True Bugs - Hemiptera • Wings - half-winged, front leathery, back membranous • Mouthparts - Piercing/sucking - beak • Metamorphosis - Incomplete • Other - plant parasites, predators

  36. True Bugs - Hemiptera

  37. More Hemiptera

  38. Cicadas - Homoptera • Wings - 2 pr, straight if present • Mouthparts - Piercing/sucking (plants) • Metamorphosis - Incomplete • Other – leaf and plant hoppers, 17 year cicada

  39. Cicadas - Homoptera

  40. Fleas - Siphonoptera • Wings - n/a • Mouthparts - Biting • Metamorphosis - Complete • Other - all parasites, flattened to move between hairs/feathers • Sense heat and jump to host.
