ases the male's likelihood of finding a mate and therefore increases his reproductive success. However, each individual needs to weigh the benefits of mating with the costs of defending a territory. 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. On the other hand, if both males are familiar with the territory, there will be a contest between the two to determine which of them stays in the territory. The most desirable sites are those that will increase the male's quota of females. These sites are generally feeding and oviposition sites, which are sought after by females. This territorial behaviour is reinforced by the fact that these sites are all concentrated. 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. The male butterflies will perch on an object at a specific height where they can observe passing flying objects. Every time they see a passing object of their own species or of a relevant species, they will fly straight towards the object until they are approximately 10 cm away. If they encounter a male, the resident male will chase him off his territory. If the resident male encounters a female, he will pursue her until she lands and mating will occur. The courtship is extended in this species. The male goes through a long chase before the female allows him to mate. He must demonstrate high performance flight.
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. Therefore, the longer a male lives, the more he can reproduce, so he has a higher fitness. Therefore, males tend to live as long as the females. In A. io the synchronous eclosion at the end of winter cause males to only mate once. 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 fem
