Spiders live among us in almost every conceivable habitat. Their ecological role, one that benefits us, is as the ultimate predators of insects. They pursue this role with instinctive dedication. More than 800 species of spiders in Ontario, very few of which are dangerous to people, yet almost a third of Canadians are afraid of spiders. Learning about these creatures helps mitigate that fear.

Spiders play a key role in the food web and are an important food source for other animals including songbirds, fish and salamanders. In Ontario, the best time for observing spiders is from late spring to early fall.
