Ecology of sexual dimorphism in spiders of the genus Metepeira (Araneae: Araneidae)


Revue Suisse de Zoologie Hors serie(2): 523-529
Ecology of sexual dimorphism in spiders of the genus Metepeira (Araneae: Araneidae)
Sexual size dimorphism was examined in three species of Metepeira in Mexico to evaluate the relationship between habitat, female aggregation, and size dimorphism. M. incrassata lived in highly productive habitats, had almost exclusively communal females, and showed little dimorphism. In contrast, Metepeira sp. lived in less productive habitats, had mostly solitary females, and showed a high degree of dimorphism, with males being much smaller than females.
