  1. Mosquito’s cycle of life By: Jonathan and Esteban Image by Esteban and Jonathan

  2. Comparison of Species • Butterflies • Start in larva stage (caterpillar) • Cocoon (pupa) • Break out into adult • Some drink blood • Dragonflies • Larva stage in still water also(4 years) • Break out of shell to become adult Source: http://mosquitoes.org/LifeCycle.html Image by: http://en.wikipedia.org/wiki/File:Blood_feeding_butterflies_5362.JPG

  3. Background • Mosquito’s four main stages • Egg • Larva • Pupa • Adult Source: http://mosquitoes.org/LifeCycle.html Image by Esteban and Jonathan

  4. Egg • Egg laid on standing water • Raft of eggs • Sporadically on top of water • Damp soil • 24 hour cycle • Raft is inch long, wide Source: http://mosquitoes.org/LifeCycle.html Image by Esteban

  5. Larva • Aka: wrigglers • Lives in water 7-14 days • Breath through siphon (tube) • During growth, skin sheds 4 times • 4th molt, next stage • inch long • Some species just lie parallel to the water Source: http://mosquitoes.org/LifeCycle.html Image by Jonathan

  6. Pupa • Aka: Tumblers • 1-4 day life cycle • Float on surface • 2 Breathing tubes called Trumpets • Doesn’t eat • “Burst Open” into adult Source: http://mosquitoes.org/LifeCycle.html Image by Jonathan

  7. Adult • Aka: Imago • Males feed on nectar of plants • Females need a “blood feast” to lay eggs • After feeding, they will rest, 3 days to make eggs • Anopheles only type to transfer Malaria • Time of attacks vary to species • Aggressiveness also depends on species Source: http://mosquitoes.org/LifeCycle.html Image by Jonathan

  8. Mortality Rate in Stages • Egg rarely die • live for 1 day • look like algae • Larva highest mortality rate • High starting population • very small changes could suffocate. • Pupa also rarely die • lasts a couple days • don’t even need to eat • Adult second highest mortality rate • females are often targeted • few can identify a male Source: http://mosquitoes.org/LifeCycle.html Image by: http://images.google.com/imgres?q=egg+mosquito&hl=en&biw=1366&b

  9. Mosquito Facts • 3,000 species worldwide • 47 species in Connecticut, largest grouping US • Got rid of bats • Mosquitos coldblooded, wont bite below 50°F • Hibernating Mosquitos live 6-8 months • 2-3 months normally Source: http://www.wwhd.org/mosquito_facts.htm Image from: http://www.fightingmalaria.gov/assets/photos/mozambique/lg_moz5.jpg

  10. Conclusion • Butterflies, Dragonflies similar cycles • Four life cycles • Egg • Larva • Pupa • Adult • Specific species vary Source: http://mosquitoes.org/LifeCycle.html Image By: http://www.arlingtonva.us/Departments/HumanServices/images/11882Life%20Cycle%20Mosquito-Final.JPG
