Transcript of Mayflies or “Fish flies”
Mayflies or “Fish flies”
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!
Mayfly Swarms• Developmental
Adaptation• More chances to
find a mate• Reduces losses
by predation
QuickTime™ and a decompressor
