Hi. I saw this moth on the side of a shed in my backyard. It is large – 3-4 inches across. Can you identify it for me? Thanks for your help.

Dear Todd,
After a bit of searching, we identified your Geometrid moth as a Common Lytrosis,
Lytrosis unitaria, thanks to this BugGuide image.  According to BugGuide:  “Forewing length 21 to 30 mm., females larger than males.”  Though BugGuide does not list any Manitoba sightings, The Moth Photographers group does list a sighting that appears to be Winnipeg.
