1. Mosquito larvae, commonly
called "wigglers"
2. Larva molts (sheds its skin) four times. The stages between molts are called instars.
3. Larvae get oxygen through a breathing tube called a siphon.
4. 4th instar larva molts it becomes a pupa.
5. Mosquito pupae, commonly called "tumblers”
6. The pupa takes oxygen through two breathing tubes called "trumpets."
7. Only female mosquitoes bite animals and drink blood.
8. Male mosquitoes do not bite, but feed on the nectar of flowers.
9. Aedes mosquitoes are attacking during daylight hours (not at night).
10. Culex mosquitoes are attack at dusk and after dark.
11. Anopheles mosquitoes are the only mosquito which transmits malaria to man.
12. The average life span of the female mosquito is 3 to 100 days; the male's is 10 to 20 days.
13. Depending on species, female mosquitoes may lay 100 to 300 eggs at a time and may average 1,000 to 3,000 during their lifespan.
14. The mosquito matures from egg to adult in 4 to 7 days.
15. Most mosquitoes remain within 1 mile of their breeding site. A few species may range up to 20 miles or more.
16. Several mosquito species are known carriers of significant diseases of man and domestic animals.
17. Mosquitoes are 140 different kinds in the world.
18. Female Mosquitoes are attracted to carbon-dioxide and will pierce the skin of people and other warm-blooded animals to suck blood, causing a painful swelling.
19. The larvae feed on algae and organic matter. They are full grown in 2 - 14 days.
20. Adults emerge after 1 - 14 days.
