Seven-spotted Lady Beetle, Coccinella septempunctata. An import.
Another seven-spot, on a fireweed stalk.
This is an eighteen-spotter, one of the many patterns of the Multicoloured Asian Lady Beetle. They're recognizable, whatever the number of spots or base colour of the wing covers, by the "W" on the pronotum. It's also an import.
I haven't seen any native ladybugs yet this year.
