Now watch this video about the ladybird’s life cycle:

(In the video we saw newly hatched ladybird larvae eating an unhatched egg. Scientists believe ladybirds lay both fertile and infertile eggs in the cluster. When aphids are in limited supply, the newly hatched larvae will feed on the infertile eggs.)

 

Read this information about the ladybird’s life cycle.

Many ladybird species (like Britain’s most common one, the seven spotted ladybird) only have one generation in a year:

  • October-February: Adult ladybirds spend winter in a dormant state, known as 'overwintering'.
  • March-April: Adult ladybirds become active and leave their overwintering sites to find food.
  • May: Male and female ladybirds mate.
  • June-July: Mated females lay eggs which hatch into immature stages called 'larvae' which pass through four instars (stages) and then form 'pupae'.
  • August: The new generation of adult ladybirds emerge from the pupae.
  • September: These new adults feed but do not mate until next spring after they have overwintered.
