Complete Metamorphosis • Insects, such as butterflies and ladybugs undergo complete metamorphosis (gross). • There are 3 distinct stages of complete metamorphosis (not counting the egg stage).
Complete Metamorphosis (cont’d)E.L.P.A • (egg) • Stage 1: Larva • *looks nothing like the adult insect • Stage 2: Pupa • *looks closer to the adult but still not there • Stage 3: Adult • We don’t need to see that again…
Incomplete Metamorphosis • Grasshoppers and Praying Mantids (for example) • Only 2 distinct stages (besides egg)
Incomplete Metamorphosis (cont’d) E.N.A. • (egg) • Stage 1: Nymph • *Looks like a miniature adult but lacks functional sex organs and some adult structures like wings • Stage 2: Adult • *
Molting • During certain times of the life cycle, insects will molt their exoskeleton in order to accommodate more growth! • http://www.youtube.com/watch?v=Bw1MFdlmWyA
