Entomology exam 3

compare holometabola larvae versus adults

• larvae - focused on feeding and growth

• adult- focused on reproduction and dispersal

overall, larvae dont compete with adult

Order Megaloptera (adults vs larvae)

• adults- riparian (close to water source)

• larvae- aquatic

• pupae- fairly mobile
