Yes, that is what I read. It is when they are trapped that they sting. I'm going to ditch my beanie and go back to wearing my hooded vest under my wetsuit. I decided not to wear my hooded vest as the water felt like it had warmed up some. That was a mistake.I wonder if that actually makes it worse because if they get in, they can't get out and they are trapped up against your skin.
I react pretty badly to any sort of sting...mosquitos, horseflies, you name it...almost like an allergic reaction.Ah, the dreaded Agua Mala !! The lady that owned the first shop I'd worked for, used to break out horribly from the little bastages, but for some reason, they never bothered me much. Some folks seemed to get zapped pretty bad, and others very little or not at all.
