Peacock Butterfly


  • Peacock butterflies are highly territorial.
  • They will pair for life.
  • Adult males claim the territory and the ones that hold the territory are most likely to get attracted by the females.
  • Males must defend the territory as well as the foraging areas, nesting sites, and watering habitats.
  • They will actively defend the range against males of other groups. One dominant male is good enough to drive off the intruders.
  • The male butterfly perches on a reasonable height to get a clear view of objects that fly pass away.
  • When threatened, peacock butterflies produce alarm calls which may warn their counterparts of the ground-based predators. But when blue tits attack butterfly will make a hissing noise.

  • A female lays as many as 400 olive-green eggs in one time. She lays eggs on the nettle leaves and plants.
  • The caterpillars are distinguished by their shiny black skin and head. Caterpillars are born 7 days after hatching.
  • The chrysalis shows brownish green body but a tinge is darker in color.
  • Caterpillars reach an average length of 42 mm.
  • The pupa is dark grey to yellow in color. Depending on temperature the pupa stage lasts 12 – 28 days.
