It looks like a horse-fly
What is a horsfly?
Horse-flies (Tabanidae) represent a family in the order of Diptera that are distributed world-wide. They are large flies that fly quickly. Adults feed on nectar while females feed on mammals blood (including humans). When they sting, it hurts much more than a mosquito! You probably want to get rid of it before going to bed!
Wasps (Hymenoptera) vs flies
You thought about a wasp because you saw a pseudo-pattern of yellow bands on the abdomen I suppose. It is actually easy to tell it is a fly (Diptera) because (1) it has only two wings, (2) it has very big eye and (3) Hymenopterans have a thin waist while diptera don't. Another noticeable trait that should make you think of a horsefly is that it flies very fast. Note by the way that hoverflies have a very distinctive pattern of black and yellow bands but are flies and don't sting.
I don't know! But someone on this website will probably be able to find out.
