Recently I've seen this bugs fly around in my home office while I'm working at night. They don't seem to appear during the day, but when I'm working late during the night (1am - 4am), they start to appear.

I think they're attracted to the lights and computer monitors.

This gave me an idea, and I got a plastic bowl, filled it with water/soap and shined a light down into it. This immediately got the attention of the bugs and I created a small little death trap.

Does anybody know what these are? If you look real close, they have strips of black and yellow across their back.
