So, is this fiction?
Kidding!!
I actually had no idea that male mosquitoes feed on plant nectar!! Absolutely none! Your well-written story is maybe not that far off actually. I've always wondered what exactly it is that attracts them to only some humans; growing up on our farm, there was a patch of field by a large forested area, and my one sister, brother and mom were always swatting frantically, but my other brother, me and my dad never got touched. It was the strangest thing. Seeing from your comments here and elsewhere, I have the feeling that they delight on your taste and smell :)
