I have sighted obviously a rare bug/fly... I have searched the entire internet for clues & wasn't able to rule out any possibilities. This was the second time I have seen this bug in the past 2 weeks. I did take pictures from my camera but for now I have included my diagram of this bug/fly. The diagram will further explain this rare sighting. If you need the pictures taken from my camera please don't hesitate to ask.
When looking at this diagram I want to remind you that this bug/fly is no bigger than a half of a centimeter.

sorry but without a picture and details of where you are based we will not be able to help you. There are just too many insects that are similar and meet some of the details you have supplied.
