For mosquito bite, you will not even know in most of the case, until you feel itchy.
So it is definitely not mosquito.
Since you give either mosquito or bee, then it will be bee.
(It is possible for something else. But I will not know what it is based on the information.)

Based on what you said, bee has the highest possibility.
As to bee, its attack is a fatal attack to itself.
