I am a birdwatcher, spend alot of time outdoors and was out there day before I found these bites. I've had tick bites, so it's not that.
I've used benadryl cream and it has helped stop the itchiness.
It could be a bug bite or a reaction to some plants in the area- if benadryl is helping, I'd keep using that and just keep an eye out for signs of them getting worse or infected- if they do, head to your doctor.
