Three-banded Ladybug

I have searched and searched for the ID for this Ladybug, but have not (yet) been able to find it. Maybe it's not a Ladybug after all? It was the tiniest thing (4-5 mm) on a small piece of fallen bark at the edge of a wooded area, in Benchlands, out past Cochrane. A few of us went to botanize this land that belongs to Erik Butters - very generous of him to lead a walk for us. Amazing that I even noticed such a tiny insect in an area of fallen logs and natural debris, but I am SO glad I did. As you can see from this much enlarged shot, it really is quite beautiful.

"This attractive Three-banded Ladybug is yellow during the summer of its birth. After the first hibernation, the elytra turn a deep red, and the bands are highlighted with a cream-colored halo." From canada-gardens.com/2ladybugs.

People in the US are being asked to watch out for some "most wanted" ladybugs that have nearly disappeared in the United States.
The three ladybugs are:
1) Coccinella novemnotata, also known as the nine-spotted ladybug or C-9;
2) Adalia bipunctata, the two-spotted ladybug;
3) C. trifasciata, the three-banded ladybug. I don't know if the Three-banded Ladybug is more common in Canada.
