Presentation Transcript

  1. Ephemeroptera • Aquatic Nymphs, winged adults • Larvae feed on aquatic plants and smaller invertabrates • Adults feed on… nothing at all!!! • Adults live only a matter of hours to days • What kind of metamorphosis is this?

  2. Ephemeroptera Nymphs (Naiads) • Have Gills! • 3 Cerci (tails) • May live for several years • Prey on mostly plants and debrie, also small invertabrates

  3. Ephemeroptera Adult • Ephemeral??? • Pair of large triangular forewings, often with a thickened leading edge • Usually a pair of reduced hindwings • Tiny antennae • Large forelegs • Usually 2-3 cerci (tails)

  4. Odonata Odonata Anisoptera Dragonfly Zygoptera Damselfly • Aquatic Nymphs, Winged Adults • Both Naiads and Adults are predacious, feeding on insects or even tiny fish and frogs • Cannot fold wings on back • Wings move independently Lestidae Spreadwings Coenagrionidae Narrow Winged Aeshnidae Darners Libellulidae Skimmers Gomphidae Clubtails

  5. Odonata Naiads • Have Posterior Gills • Lower jaw extends to catch prey • Tend to live on bottom of streams ponds • Anisoptera Nymphs: Short and Wide • Zygoptera Nymphs: Long and Narrow

  6. DragonFliesVs Damselflies

  7. Anisoptera: Aeshnidae(Darners) • Clear Wings • Large Eyes Touch • Tend to have bright bodies: Blue, Green, and Brown • Live near ponds and streams

  8. Anisoptera: Gomphidae (Clubtails) • Have separated eyes • Large, sprawling legs • Club like widening at end of abdomen

  9. Anisoptera: Libellulidae (skimmers) • Bright colored bodies • Bodies are shorter than wingspan • Wings often have bands or spots

  10. Zygoptera: Coenagrionidae (Narrow-Winged) • Most common Damselflies • Wings held upright at rest • Bright colored bodies • Clear wings • Naiads have leafy gills

  11. Zygoptera: Lestidae • Wings diverge at rest • Wings clear, bodies colored • Naiads have stalk like gills with rounded ends

  12. Dichotomous Keys • Based on dichotomies, you must choose one of two options • By repeating this step, you can narrow down to more and more specific classifications • Answers often involve whether a diagnostic trait is present • Example: Does this insect have wings?

  13. Does it have cerci (tails?)

  14. Odonata Odonata Anisoptera Dragonfly Zygoptera Damselfly • Does it have a stout body and hold its wings flat at rest? • Is Body Longer than Wingspan? • Do its eyes touch at top of head? Lestidae Spreadwings Coenagrionidae Narrow Winged Aeshnidae Darners Libellulidae Skimmers Gomphidae Clubtails

  15. How the key would look • It has wings 4 It doesn’t have wings 2 • It has six legs 3 It doesn’t have six legs it’s not an insect • Its ancestors have wings 4 It never had wings apterygota • It only lives for a day ephemeroptera It lives for many days 5 • It has bulging eyes Zygoptera Its eyes do not bulge Anisoptera
