OdonataC. Phasmatodea Current LectureI. Magic Trick DemoII. Orders of the DayA. Ephemeroptera1. Mayflies = “short lived”2. Adults live for about 24-48 hours3. 2,000 species 4. 2 pairs of wings held above the body5. Adult metamorphosis vestigial6. Simple metamorphosis (incomplete)7. 2-3 long filaments also known as cerci8. The immature aquatic nymphs (Naiads) are predators 9. As predators they eat plant life & mosquito larvae10. Have a pre-adult stage called sub-amigo that doesn’t have reproductive organs 11. Mate by swarming because the odds of finding a mate within 24-48 hours are greater 12. Collection: close to water, gas stations, Theatre Complex, at light traps13. Economics: They contribute to the food web and are environmental indicators 14. Preserved in alcoholB. Odonata1. Dragonflies & Damselflies (snake doctors), Mosquito Hawks/DarnersThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.2. 5,000 species3. 2 pairs of wings: can be out or folded depending on the species4. Chewing mouthparts5. Simple metamorphosis (incomplete)6. Aquatic immatures are known as Naiads7. The are predators throughout all stages of life8. Short antennae9. They use their legs as baskets and immatures have a “mask” like structure over their face10. Most of the species have large compound eyes 11. Collection: around rivers and ponds, also around Research Park in the Spring12. Economics: environmental indicators of water quality and are beneficial as predators13. Preservation: Immatures are preserved in alcohol Adults are preserved on pins or points C. Phasmatodea (Phasmida)1. Walking Sticks and Leaf Insects (Ghosts)2. 2,000 species3. Some species are very small wings; generally secondarily wingless4. Chewing mouthparts  Plant eaters = Herbivores 5. Simple metamorphosis (gradual) 6. Able to blend into a background because of their cryptic body7. Arboreal (non-social)8. Parthenogenesis is common = asexual 9. Collection: tall grass in fields and shrubby areas, tips of branches; if you shake the trees they usually just fall out10. Economics: Can be a problem on high value crops such as tea leaves, but other than that they are generally not a problem 11. Preservation: Immatures are preserved in alcohol Adults are preserved on pins or
