Second night in a static van. There are hundreds of mosquitoes around but I’ve been sleeping under a duvet, surely they wouldn’t have bitten my knees? 
Not itchy at all.
I also have bites on my face but they’re not so obvious. A few on my hands. DH doesn’t appear to have anything much, one DC’s cheeks are covered in red spots like a sprinkling of freckles.
What are they?
