Ladybug life-cycle, an Illustrated Picture

Ladybug life cycleThe life-cycle of ladybug has four stages: the egg stage, the larvae stage, the pupa stage, and the adult ladybug stage. Here is illustrated pictures of Ladybug life-cycle with brave explanation of each stage of life-cycle.

  1. The egg stage; In order to protect eggs from being seen by flying predators, ladybugs lay their eggs on the underside of leaves. Ladybug will lay from ten to fifteen eggs in one place. The eggs of ladybug is look like yellow jellybeans.
  2. The larvae stage; The larva of ladybug eat tiny mites or aphids. Newborn larvae look sort of like tiny alligators. In a few days the size of larvae will be larger and ready  to molt and they keep molting for as long as they are growing.
  3. The pupa stage; During the pupa stage, the larvae are going through a metamorphosis into a ladybug.
  4. The adult ladybug stage; The full grown ladybug will emerge when metamorphosis is complete. This newborn ladybug look soft and pink or very pale for a couple of hours until its shell becomes hard. As the shell hardens it also gains pigment.
