Telling the truth is always the best, a lesson parents are eager to teach young ones. Welcome, Flo, the Lyin' Fly, to Hermie's delightful world. Like the little boy who cried "wolf," Flo thinks it's fun to tell stories that are not true. When her friends discover they can't trust her, they refuse to believe her when there's real trouble. Drawing from Proverbs 19:5, which says no one gets away with a lie, Flo the Lyin' Fly sets out to teach children, through incredibly humorous situations the importance of telling the truth no matter what the circumstance.
In a prequel to Hermie: A Common Caterpillar, Hermie introduces Flo, a sweet young fly who learns an important lesson about telling the truth and nothing but the truth.
