Not an entomologist so just my option is based on info from local gardeners and the interwebs, the article you posted is interesting, I knew that the Asian species did not need to have the “m” and your picture kinda looks like the head of the 10 spotted in your article but too many spots on the body. The article I posted shows a bunch of the Asian bugs hibernating in a house and that picture shows a lot of veriaty including a few that look like your pic. I would still say Aaian lady bettle but not an entomologist so ¯\(ツ)/¯
