Hi there,
I’m hoping you help me out by telling me what kind of spider I found at my house.
Signature: Doesn’t matter

Shamrock Spider

Shamrock Spider

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.”
