List four reasons why the insects are so successful.
- Only invertabae that can fly
- Reproduce quick, live shirt lives
- Small which means they can fit in any environment
- Wide diversity of 10 million species which gives feeding and reproductive advantages
List the five basic structural features of Arthropods.
- Chitinous exoskeleton
- Molting (shedding), doesn’t grow
- Head, thorax, abdomen (3 basic structures)
- Bilateral symmetry
- Open circulatory system
- (If needed) well developed nervous system
What is incomplete metamorphosis?
Eggs -> nymph -> adult
What is complete metamorphosis? What is the advantage to four life cycles?
Egg -> larva -> pupa-> adult
Advantage is you can pass winter and hatch at the start of summer so you’re ready to go and not still going trough the stages
