Seems like a plausible explanation but how do you have any idea which species bit you in order to be able to draw a conclusion that there's a correlation?
Speaking personally - not always do I notice the mosquito.
But I have noticed often enough to note the difference. For me, the smaller, more stealthy mosquitos give me the small, temporary bump, but the larger more noticeable ones like the tiger mosquito or what we call zebra mosquitos (I think they are actually western encephalitis mosquitos (!)) have a more dramatic reaction.
