Description • Mainly aquatic insects • Nymphs live for 1 year.
Description • Flying adults live less than a day. • Also called Fish flies
Metamorphosis • Incomplete & Complete Metamorphosis • Developmental Adaptation
Mayfly Metamorphosis Winged adults emerge from aquatic nymphs
Mayfly Nymphs • Feathery Gills (Structural Adaptation) • Many species can vibrate gills (Behavioral Adaptation)
Mayfly Nymphs • Live under stones or in burrows • Behavioral Adaptation
Mayfly Nymphs • Cerci • Defensive adaptation (Structural) • “Scorpion Stance”
Mayfly Reproduction • Adults only purpose is to reproduce • Emerge in SWARMS!
