Comments & ID Thoughts

Spider was witnessed crossing an asphalt road inside Earl Rowe Provincial Park in Ontario Canada. I believe it to be a Shamrock orb-weaver (Araneus trifolium). It seemed to be on a mission to travel from point a to point b; wherever that is. The are is lightly forested, with mixed meadows and farm land nearby.

Yes, A. trifolium. Filed. 🙂

Can you tell by placement of dots on abdomen? Looks similar to cross orb weaver is why I ask. Looks like a double cross so I do see a slight difference.

The banding on the legs is notably bolder than a Corss Orb-weaver’s (Araneus diadematus). When I have doubts about the pattern on the abdomen I look at the legs.
