Abstract

Many spiders live in narrowly defined environments, limited by physical conditions such as temperature, humidity, wind and light intensity, and also by biological factors such as type of vegetation, availability of prey, competitors and natural enemies. The family Araneidae is the main family of spiders that build orbicular webs. The spider of the present study, Eustala perfida, occurs preferentially inside the forest, along the trunks of trees, building its web in regions where there is a depression in the trunk. It has cryptic coloration similar to mosses and lichens, adaptation that confers dual advantage to the specie, as it would hardly be perceived by their prey and their predators. The lack of studies on this genus of spiders, their life history and ecological rolesit plays, led to the preparation of this project, which will be realized at the Serra Japi - Jundiaí (SP) and aims to elucidate aspects of the natural history and population ecology of Eustala perfida, such as spatial distribution, substrate specificity, phenology, population dynamics and diversity of prey.
