"This arachnid is generally found in treetops, weaving webs to catch birds and monkeys."
Folio Bruti[src]

Giant Spiders are a large species of spider that inhabits woodland. They feed on birds and monkeys, which they trap in large webs that they weave in treetops. They are most vulnerable to the Incendio and Wingardium Leviosa spells, but were impervious to the Diffindo charm.[1] One could find Giant Spiders in the grounds of Hogwarts Castle during the 1993-1994 school year.[1]
