I don't know if it's just me but I've been asking this question for ages and I've never been provided with a reasonable answer.. The Sand fly is a magnificent creature that feeds on its host by injecting its saliva to the skin to allow easy passage of the blood... Interesting isn't it..? They are so small that they look like a well cut strand of hair.. There wings are practically invisible due to their miniature state..
Now to the question.. I've observed that the Sand fly is attracted to some people and it's not to others.. I watch my Fiancé complaining each day about been bitten by one and I just take a big laugh telling her they're attracted to her just like I am to her.. I've never been bitten by one or maybe I'm losing my sense of touch to feel their bite.. I've seen people complain about been bitten by these blood thirsty vampires and others don't.., so what likely could be the reason behind these attraction.. Thanks and looking forward to your responses..

Everybody is afraid of Hiv/aids, they won't be attracted to people they don't trust.

By the way, what is sand fly?
