Most people don’t think about their blood type unless they need surgery or are planning to donate blood. But we can learn more from our blood types than simply whether or not we can safely accept a transfusion from a donor.
While there is some weak and inconclusive indication for blood type preference from older publications, the research persistently shows CO2 plume, body odor produced by certain bacteria and heat (mostly in that order to guide the mozzie from several meters away to the exact blood vessel) as most important cues that lead to host identification, attraction and feeding, through all tested anthropophilic/mammalophilic genera within the family Culicidae.
