Not a fan of bugs . . . gnats especially. I know that they have their purpose and all that. I'm guessing as fodder for other bigger potentially more annoying bugs.
What I don't get about gnats . . . pronounced guh-nats . . . is why they always go for the eyes. The second I step out the door *boom* there's a gnat making a beeline for my eyeball. If, by some miracle I am able to ward off the pest, the creature will hover right in front my field of vision waiting for an opening. The thing I don't understand is that if the stupid little bug did manage to fly into my eye . . . besides causing irritation and pain to me . . . it is surely certain death to the bug. So what is drive behind the suicide flight?
The answer . . . although seemingly paradoxical in nature . . . is quite elementary, actually. Survival.
Gnats . . . or eye flies . . . require a substance humans (and other animals) secrete for reproductive purposes. That substance . . . dum dee dum . . . is found in the eye. Or your tear ducts to be more specific. They need the minerals found in tears to produce their eggs. So strong is their drive to carry on the family name they will risk an early demise.
