I’m hoping you help me out by telling me what kind of spider I found at my house.
Signature: Doesn’t matter
This is a harmless female Orbweaver, and though we sometimes have problems with species identifications in the family, we are confident this is a Shamrock Spider, Araneus trifolium, a species found throughout the northern regions of North America. Here is a matching BugGuide image, also from Ontario. According to BugGuide: “Araneus trifolium female occurs in a variety of colors.”
