Any ideas? (It was itchy and so it was scratched, yesterday.)
We can describe the bite from pictures as you didn’t provide any information.
- single bite
- small bite
- scratched until it made like a wound or puncture.
- has a large reddish area around it
So that we can suggest a mosquito or an ant that can make small single bite at one site and leave reddish so itchy bitten area. read about allergic reaction after mosquito bites
However some skin conditions can cause bite-like marks on the skin and induce scratching.
