Lepidoptera is a large group containing butterflies and moths. Currently there are more than 157,000 described species with at least as many as this still undescribed.

Life cycle

Lepidoptera have a holometabolous life cycle, meaning they have four separate stages: 

  • egg
  • larva
  • pupa
  • adult

A few species lack males, meaning the females are parthenogenetic, which allows them to successfully reproduce without having mated (virgin birth).
