Thanks Blaine.. I was not sur
Thanks Blaine.. I was not sure about C. septempunctata because of the absence of these 2 white spots at the base of the elytra, and the presence of that black "V" shape and these clearly visible dorsal lines.. but the black spots are there.

it's possible...
there is a boreal Coccinella I am not considering. Maybe we should move it back to the genus level for now? I no longer have my book on the coccinellids of AMerica, so I can't look it up.

This Lady puzzle me a lot. I have added 2 photos of it. We could see an additionnal spot on the shoulder, which could make it a nine spot lady beetle, but the sutural margin on the elytra is not black, and there is that black V shape on the elytra and these clearly visible line...??

Coccinella septempunctata
you were right the first time. This is most certainly the brute Coccinella septempunctata. Keys well (venter image would assure it) using Gordon '85. Suture not dark. Apical pronotal margin not entirely pale. Head with two well-separated spots, not a white band. BIG. Unfortunately, there is no native boreal species to be considered.
The white scutellar markings are not required. The "black 'v' and dorsal lines" are not elytra markings, but structures. Well, the black v is more of artifact of what's underneath the elytra and the folding of the flying wings. Lastly, the humeral markings appear or not on many ladies, so they are not reliable traits.
just another introduced brute (a somewhat faded one at that)
