I think lovebugs are just a Gulf Coast thing and that they are native to South America. I don' t think anything eats them. I've never seen anything prey on them at all. Supposedly, spraying Pam on your car will keep them from sticking, but I have not tried it. I do know that if you do not wash them off, their guts are acidic and will cause the paint on your car to peel. In spite of all that, I love the little boogers...they are so cute and funny! If they just didn't mess my car up...but oh well, they are far from the most irritating thing in life.
