Moved from Brumoides septentrionis.

Created a node for the subspecies B. s. septentrionis.

Thanks Beatriz, for your careful updates, and retention of relevant comments.

Brumoides septentrionis
According to Gordon's ref.(1), the Variable Lady Beetle, an introduced species, is confined to Florida. And BugGuide posts to-date confirm that distro.

Rather, this is Brumoides septentrionis septentrionis (Weise) 1885, generally distro throughout the western states and Canada (Rockies and Great Plains), except not reaching the coast, west of the Cascade range. Your location appears to be on the western extent of the stated distro as it crosses the border from mid-Washington.
Key here is the totally black pronotum, which sets it apart from any Hyperaspini, a few of which can superfically resemble the eytral pattern. (Brumoides is actually in a altogether different subfamily: Chilocorinae) Beyond that, Gordon states "Lenght 2.9-3.0mm, Form oval. The color pattern of this subspecies is quite variable" (but yours matches one of patterns illustrated very well).

great find, and another new genus and species for BugGuide :) Keep them coming! You are in prime ladybird country for many species currently not posted in BugGuide (or anywhere else on the web for that matter). Look especially for the small ones, and try to get a good shot of the head and pronotum!

What is it eating?
It seems to be feeding on some sort of larva. I see a drop of fluid at the tip of the prey's abdomen, if that is what it is.

Moved from Beetles.
