Arachnids make up an exclusive predator group. Eating habit makes the arthropods to move around in search for hunting or building traps with silk threads. In order to know the araneofauna of the Godoy’s Forest State Park, pitfall-like traps were installed inside the forest, edge and adjacent area predominantly grassy. Collections were carried out fortnightly, in the period of a year, separating what was collected during the day and during the night. One hundred and twenty-one individuals were collected, belonging to 18 families where Lycosidae and Theridiidae were the most abundant, although Lyniphiidae family has prevailed in the forest area. Young individuals prevailed. It is concluded that the highest frequency and abundance of young individuals may be directly related to its dispersal and spiders belonging to the Lycosidae, Zoridae and Theridiidae families, being able to be used as bioindicators.
