This evening I found this ladybug on my windowsill. I think this is a Multicolored Asian Lady Beetle (Harmonia axyridis). As you might guess from the name, this is not a native species (unlike this native Spotted Lady Beetle from Iowa). This beetle was introduced as a agricultural pest control at several points in the 20th century and became widespread in the 1980s and 1990s.
