Pond olive

Cloeon dipterum s.l.
Pond Olive
  • Cloeon dipterum s.l. is a mayfly species complex with a Holarctic distribution.
  • Unlike most mayflies, Cloeon has only one pair of wings.
  • Males and females have different eye structures.
  • Females die shortly after laying eggs.
  • Eggs hatch immediately after they are laid.
  • It can molt over 10 times to complete larval development.
  • Most mayfly adults live only a few hours, but the pond olive mayfly can live for a week or more.
  • It is one of the few mayflies able to colonise oceanic islands, probably due to its long adult life, asexual reproduction, and ovoviviparous females.
  • Mayflies had already been around for 100 million years when the dinosaurs arrived.
  • Mayflies can be very abundant and an important food source for birds and fish.
