Oh my! This is a great work of fiction which brought back to my mind a question I used to ask when I was a bit more innocent.
As Christians we believe that sin brought in all the negativity we see. So what were the female mosquitoes feeding on before sin?
My guess is that either they were feeding on fruit juice like their male counterparts or they were in a kind of beneficial symbiotic relationship with some animals.
Your post gat me thinking!
Mosquitoes were biting animals for tens of millions of years before humans projected their sense of sin on the animal world.
I like this theosophical philosophical interpretation of the story. You should read my comment. We had similar thoughts :)
