Mosquito Lifecycle Stages Explained

The lifecycle of a mosquito involves distinct phases of development. Understanding the correct sequence is key to identifying its different stages.

Sequence of Mosquito Development

Mosquitoes undergo complete metamorphosis. The four main stages occur in a specific, fixed order:

  • Egg: The lifecycle begins when eggs are laid, typically in water or damp areas.
  • Larva: The egg hatches into a larva, an aquatic stage often called a "wriggler". It breathes air and feeds on organic matter.
  • Pupa: The larva develops into a pupa, another aquatic stage known as a "tumbler". This is a non-feeding transitional stage where the adult form develops.
  • Adult (Imago): The pupa transforms into the winged adult mosquito, which can fly, feed, and reproduce, starting the cycle over.

The correct progression through these stages is: Egg → Larva → Pupa → Adult (Imago).
