Bee sting: Could be a simple mosquito bite, bee sting, or lyme disease from a tick. I recommend getting it checked out by a doctor, especially if the red splotch grows in size or starts to look like a ring. If you have fevers, achiness, or other symptoms in the next week, also go see a doctor.

Insect bite: Sounds like local allergic reaction to the insect bite, if the area of redness is not spreading and does not feel warmer than the surrounding normal skin then just apply over the counter 1% Hydrocortisone cream and take appropriate dose of Benadryl (diphenhydramine) to stop the reaction and itching. If any tenderness or warmth then chance of secondary infection and needs to be seen by physician.
