What kind of bug is this?

I found it in the windowsill of my house. (Manitoba, Canada). It was all black, except for where its wings would be under, which were bright red. It had long antennae, and longish legs. It also had a bit of white on its face. It was a VERY fast flyer. It's size was about 1 or 1.5 cm long. When it flew around, it landed on my hand and my shirt on different occasions, and didn't sting, bite, or do anything except fly away again after a couple of seconds. Actually, it was quite a nice bug, as far as bugs go. Just wondering what it could be, is all.
