Meaning intimidating eyes
The adult butterflies drink nectar from a wide variety of flowering plants, including buddleia, willows, dandelions, wild marjoram, danewort, hemp agrimony, and clover; they also utilize tree sap and rotten fruit.Aglais io employs a monandrous mating system, which means that they only mate with one partner for a period of time.The peacock can be found in woods, fields, meadows, pastures, parks, and gardens, and from lowlands up to 2,500 metres (8,200 ft) elevation.It is a relatively common butterfly seen in many European parks and gardens.If the valuable resources were dispersed, there would be less observable territorial behaviour.To find mates and defend their territory, Aglais io exhibits perching behaviour.Aglais io exhibits this type of territorial behaviour, and must defend a desirable territory from other males.If only one of the males knows the territory well, he will successfully chase off any intruders.
The chrysalis may be either grey, brown, or green in colour and may have a blackish tinge.
The monandrous mating system has caused the evolution of a shorter life span in males of this species.
In polygynous butterflies, the male's reproductive success is largely dependent on life span.
Their reproductive success is therefore not linked to how long they live, and there is no selective pressure to live longer.
Therefore, the life span of males is shorter than the lifespan of the females.
