Observed on the trunk of an Acer saccharinum. My tentative guess is Chilocorus bipustulatus based on this page:

size?
Unusual color...not many coccinellids with red-on-red maculations? Unless it's an effect of the lighting.

 
Small --
smaller than Cycloneda munda. It really was that pretty. My camera depicts oranges and reds particularly well.

 
Chilocorus bipustulatus (Linn
Chilocorus bipustulatus (Linneaus, 1758). It's an introduced species from Europe. We see it uncommonly here in the San Joaquin Valley of California.

 
Occasionally on East Coast, too
There's one on BG from New Jersey this year. I don't know if the species can become established in MD or NJ, the weather can get very cold in the winter. It'll be interesting to see where else the species turns up in the next few years, and maybe another population will become established on a warm part of the East Coast. (Florida, perhaps? - a haven for non-native Chilocorus already.)

 
It
seems to have survived Baltimore's snowiest winter since record-keeping began in 1883.

very cool info!
Thanks for linking the new post here, I wonder if there's a small local population or just one very photogenic and cold-hardy beetle!

 
It is a striking little beetl
It is a striking little beetle, with its red-brown color and bright red-orange spots. I usually associate them with bad infestations of Brown Soft Scale (Coccus hesperidum) or European Fruit Lecanium (Parthenolecanium corni) in shrubs in Rosaceae.

 
If
the species does establish somewhere further south of here, perhaps there will be population irruptions leading to northward "migrations" in some years as some butterflies are apt to do?
