What is this??

Help! What is this?? Babysitter and me agree that it is not a mosquito bite. (They are usually swollen...this one is completely flat) also not chickenpox...its just in her face and not over her whole body and it doesn't hurt when I touch it. We suspect some other insect bite. We are also all sick with a stomach bug since Monday with vomiting and diarrhea...so not sure if it could be related. We live in Florida. I called pediatrician medical line and waiting for a call back.
